Remove OCaml debugger plugin

In January Davide sent an e-mail to the mailing list to suggest removing
unmaintained language plugins such as Go and Java. The plan was to have
some cool down period to allow users to speak up, however after that the
plugins were never actually removed.

This patch removes the OCaml debugger plugin.

The plugin can be added again in the future if it is mature enough both
in terms of testing and maintenance commitment.
