setup of vwatch for jboss tools installations

1. use the install robot and then run versionwatch aginst JBoss Tools install with all of central content installed.

usecases:

• find missing/weird versions
• duplicate components
• get list of potential unnecessary plugins in TP

2. document how to do installs for Eclipse, JBT or JBDS BYOE via commandline for setting up the footprint of installs against which to do baseline version watches – pre-existing doc here:

https://devstudio.redhat.com/download/scripted-install/

3. test #2 to ensure it works, and that a mix of "studio" and "eclipse" folders can be used in a vwatch report

4. create new jobs (or extend existing ones) to provide reports about JBT, JBT+Central, JBT+Central+EA; repeat for JBDS combinations. Maybe migrate jobs to matrixes?

Additionally, now that jbdevstudio-qa/vwatch has moved to jbosstools-versionwatch, we should also do these two things:

5. remove all refs to QA Jenkins file paths to make *.sh scripts more generic

6. migrate those internal file paths into jenkins config.xml files so they're not stored in public repos
