JBIDE-16245 Show correct version of integration tests repo web page

Updated site/pom.xml to generate the proper version in the repo html
page. This also removes the explicit version definition for the site.
Launchers and TestSuites

changes:
- added swtbot launcher for OpenShift Online and OpenShift enterprise
- fix OpenShift enterprise labels for cartridges and applications
- added MySQL and PostgreSQL cartridge tests
Workaround for intermittent/inconsistent situation where
newly created task is not visible.
Seems to be a timing issue in the UI - dependent on
CPU speed? Only seeing this sometimes on Jenkins - never locally.
