SLING-3685 - Document and further automate the IDE tooling release
process

Move the eclipse-test plugin to a profile named 'eclipse-test', active
by default. This will allow the module to be excluded on-demand from the
reactor, as with Tycho 0.20.0 the maven-source-plugin and the
tycho-p2-plugin don't play nice in the same reactor build.

SLING-3685 - Document and further automate the IDE tooling release
process

Execute the maven-source-plugin during the 'sign' profile, and make sure
that the proper artifacts are included:

- include Eclipse plug-in specific artifacts in the output by making
them part of the Maven resources
- use the custom MANIFEST.MF whenever present
