Infinispan project versioning change

Mainly for consistency reason, starting with the next Infinispan releases, we'll switch to JBoss' release naming conventions. In practical terms this means that the names of the releases(Maven artifacts, JIRA) would be different.
E.g.

Old release name	New release name
5.2.0.ALPHA2	5.2.0.Alpha3
5.1.0.BETA1	5.2.0.Beta1
5.1.0.CR1	5.2.0.CR1
5.1.0.FINAL	5.2.0.Final

The names of the releases in JIRA have also been changed startting with 5.1.2.Alpha3.

Cheers,
