Merge redundant build jobs into a single template

Merge redundant build jobs into a single template

Not necessary to define multiple templates that differ only in 1 line of
the Maven Goals parameter. This patch removes the redundant job
templates and adds a new EXTRA_MVN_OPTS parameter that can optionally be
used to pass additional parameters if necessary both at runtime and per
stream by passing the {extra-mvn-opts} jjb parameter.

Additionally:

    - Removes archiving of sar data in Jenkins (we shouldn't be
      archiving anything in Jenkins).
    - Revert archiving of **.zip files as we are able to produce
      staging repos now.
