TEIIDDES-1807: Simplifies RESTEasy war generation wizard

* Removes the engine and common-core jar locations from the war generation
  wizard since they are unnecessary since we already include the contents
  of these jars in the teiid client runtime plugins.

* ModelerCore fetches the runtime path of the targeted teiid server version
  from the relevant teiid client runtime plugin.

* Adds TeiidServerVersion isGreaterThan and isLessThan methods for use
  with question of if targeted version greater than specific version.

* Updates to the runtime plugin submodules in accordance with changes to the
  IExecutionAdminFactory interface.
Merge pull request #219 from phantomjinx/master
