Refactors VM Schedule to make it more generic & add option to schedule min & max for autoscaling groups

[vishesh92]

Description

Documentation PR: apache/cloudstack-documentation#650

This PR refactors the VM schedule to make it more generic and allow creation of scheduled actions based on cron format for other resources with minimal changes. Apart from the existing schedules for VM, this PR adds support for scheduling min & max members of a autoscaling group.

Existing VM Schedule related APIs have been marked as deprecated (Used @Deprecated annotation but still available for use.).

Existing vm_schedule & related tables are renamed and reused to store schedules for different resource types (VM & ASG for now). After these changes, it should be easy to add cron based schedules to other resources like networks, VRs, etc.

Details

This pull request introduces a new, generic resource scheduling API for CloudStack, deprecating the previous VM-specific schedule commands and events. The main changes include adding new CRUD API commands for resource schedules, updating event types to support generic resource scheduling, and refactoring the event-to-entity mapping to use the new ResourceSchedule class. The changes also update the VM schedule command to use the new manager and mark it as deprecated.

Resource Scheduling API and Event Refactoring:

• Added new API commands for resource schedule management: CreateResourceScheduleCmd, UpdateResourceScheduleCmd, DeleteResourceScheduleCmd, and ListResourceScheduleCmd, supporting schedule creation, update, deletion, and listing for any resource type. [1] [2] [3] [4]
• Updated event types in EventTypes.java to introduce generic resource schedule CRUD events (SCHEDULE.CREATE, SCHEDULE.UPDATE, SCHEDULE.DELETE) and reclassified VM schedule events as action-execution only. Also added an autoscale group schedule update event. [1] [2]
• Refactored event-to-entity mapping in EventTypes.java to map new schedule events to ResourceSchedule and removed references to the old VMSchedule class.
• Updated imports and manager usage in the deprecated CreateVMScheduleCmd to use ResourceScheduleManager instead of VMScheduleManager, and marked the command as @Deprecated.
• Changed imports in EventTypes.java to use ResourceSchedule instead of the removed VMSchedule.

New generic schedule APIs

createResourceSchedule

Creates a schedule for a supported resource type.

• Required params
  • resourcetype (string)
  • resourceid (string; UUID or numeric ID path is resolved internally)
  • schedule (cron expression)
  • timezone (timezone string)
  • action (resource-specific action)
• Optional params
  • description
  • startdate (defaults to current time + 1 minute if omitted)
  • enddate
  • enabled (defaults to true)
  • details (map, action/resource-specific)
• Validation highlights
  • Invalid/unsupported resourcetype is rejected.
  • Resource must exist and be schedulable for that type.
  • action is validated by the resource worker.
  • startdate cannot be in the past; enddate cannot be in the past or before startdate.
• Response object
  • ResourceScheduleResponse with fields: id, resourcetype, resourceid, description, schedule, timezone, action, enabled, startdate, enddate, details, created.

listResourceSchedule

Lists schedules for a given resource.

• Required params
  • resourcetype
  • resourceid
• Optional params
  • id
  • ids (list)
  • action
  • enabled
  • pagination (page, pagesize)
• Behavior
  • Action filter is parsed/validated per resource type.
  • Returns list of ResourceScheduleResponse.

updateResourceSchedule

Updates an existing schedule.

• Required params
  • id
• Optional params
  • description
  • schedule
  • timezone
  • startdate
  • enddate
  • enabled
  • details (map)
• Behavior
  • Supports partial updates.
  • If details is provided as an empty map, existing schedule details are removed.
  • If details is provided with entries, details are replaced/saved.
  • If details is provided as null, details are ignored.
• Validation highlights
  • Same date/time consistency checks as create path when schedule timing fields are changed.

deleteResourceSchedule

Deletes schedule(s) scoped to a resource.

• Required params
  • resourcetype
  • resourceid
• Optional params
  • id
  • ids
• Behavior
  • Removes selected schedules (or all matching schedules in scope if no specific IDs provided).

---

AutoScale VM Group schedule specifics (resourcetype=AutoScaleVmGroup)

• Supported action: UPDATE.
• details map is required and currently supports only:
  • minmembers
  • maxmembers
• Both keys must be present and parse as integers.
• Additional keys are rejected.
• Min/max values are validated using AutoScale min/max member validation logic.
• At runtime, scheduled execution triggers updateAutoScaleVmGroup with minmembers and maxmembers from schedule details.

---

Legacy VM schedule compatibility

Legacy VM schedule APIs remain available (deprecated wrappers):

• createVMSchedule
• listVMSchedule
• updateVMSchedule
• deleteVMSchedule

These continue to route through the same underlying resource schedule manager for VirtualMachine scheduling.

Pull request overview

This PR generalizes the existing VM scheduling feature into a resource-agnostic “Resource Schedule” system (API, persistence, workers, and UI), while keeping legacy VM schedule APIs as deprecated wrappers.

Changes:

• Introduces generic create/list/update/deleteResourceSchedule APIs with a worker-based execution model (BaseScheduleWorker + VMScheduleWorker).
• Migrates DB schema from vm_schedule / vm_scheduled_job to resource_schedule / resource_scheduled_job and adds resource_schedule_details.
• Updates the UI and integration/unit tests to use the new resource schedule APIs (with legacy VM schedule APIs mapped to the new backend).

ui/src/views/compute/ResourceSchedules.vue:346

• apiParams is populated only from createResourceSchedule. If a role can list schedules but cannot create them, $getApiParams('createResourceSchedule') returns {}, and the template’s apiParams.<param>.description accesses will throw even though the “Add” button is disabled. Consider populating apiParams from whichever schedule API is available (e.g. create/update) and/or guarding template access with optional chaining / defaults so the tab can render read-only.
  ui/src/views/compute/ResourceSchedules.vue:375
• The watcher on resource is deep: true, so any reactive change inside the resource object (e.g. VM state updates) will re-trigger fetchSchedules() and can cause unnecessary API traffic. Watching only resource.id (or using a shallow watch) should be sufficient and avoids repeated list calls.

ui/src/views/compute/InstanceTab.vue:1

• This import points to ResourceSchedules.vue, but the refactor shown updates ui/src/views/compute/InstanceSchedules.vue in-place (including setting name: 'ResourceSchedules'). If ResourceSchedules.vue is not actually present/renamed in the filesystem, the UI will fail to build. Either rename InstanceSchedules.vue to ResourceSchedules.vue (updating routes/async imports too) or adjust imports to the actual file path.
  server/src/main/java/com/cloud/network/as/AutoScaleManagerImpl.java:1
• The exception message is missing a space after ) in ")cannot be greater than", producing a user-facing typo. Update the string to include the missing space (and consider also standardizing the message format with the other validation errors).

• This uses a list comprehension purely for side effects, which is discouraged and makes intent less clear. Replace it with a simple for k, v in kwargs.items(): setattr(cmd, k, v) loop.
