Support for lab contextual topic names.

This work allows a drools application, with its drl
template to refer to the topic name by its invariable
canonical name, ie. POLICY-CL-MGT.    Since the drl
is a design time artifact, it is desired to know topics
by its canonical non-changeable name.

The actual per lab environment topic name may change
on a per deployment basis, for example POLICY-CL-MGT-WINDRIVER
or POLICY-CL-MGT-TLAB.   The template can still use
POLICY-CL-MGT without modification but the actual installation
configuration would use the "effectiveTopic" property to
point to the right topic on a per lab basis.

This also helps with installation (long story) since
the canonical topics will be known ahead of time.
