Add support for Ring web framework

[bitterpanda63]

Should add support for: https://github.com/ring-clojure/ring
And add support for the Clojure language (meaning docs, sample apps, ...)

[bitterpanda63]

First issue arises with embedding the java agent, since most clojure projects use: https://github.com/technomancy/leiningen, and with clojure being a more-or-less dynamic language it might prove more difficult.
Update: Should be possible using jvm-opts, but have not tested it yet: https://leiningen.org/tutorial.html#setting-jvm-options
