Fixes the possibility of a teiid version having additional components

* Code naively assumes that a teiid server version will have a maximum of
  3 components. However, version such as 8.4.0.beta2 has 4 components
  causing the minor and micro version fields to not be set, resulting in
  incorrect assignment of runtimes clients.

* This addresses this possibility by ignoring remaining components but
  ensuring that the first 3 components have been correctly set.

TEIIDDES-1710: Adds teiid 8.4 runtime client submodule and test plugin

TEIIDDES-1701: Small bug fixes for refactoring functions

* RelatedResourceFinder
 * Typo for ALL relationship.

* RefactorResourceUtils
 * Caters for real possibility that a group name appears in an SQL statement
   line more than once, eg. SELECT SourceModel.ID, SourceModel.name, rather
   than only finding the first.

* RenameResourceRefactoring
 * Only if SQL edits have been added to the TextFileChange should it be
   added as a change. Otherwise, an empty change object is added and makes
   no sense.
