1070326 - (JON3-42) RFE: Allow AS7 deployments to provide version in the artifact name
Adding one more thing to this feature, prevent discovery of siblings
resolving to the same resource key.  In the somewhat unlikely case that
two distinct sibling deployments resolve down to the same logical
deployment, don't let it get past discovery.  For example, if the user
has app-1.0.war and app-2.0.war and these are *really* different apps (and
they would probably have to be since EAP would stop deployment if they
had the same context).  In this case both would be seen as app.war, and
that is a problem on the RHQ side.  In this sutuation generate an
agent log warning that hopefully helps a user resolve the issue.

Note that resource upgrade already prevents an upgrade of siblings with
the same key, so this is an analogous change.
