[hibernate-dev] [OGM] Hibernat OGM contrib repository

If I understand correctly the consensus for the contrib dialects is:
* Keep the same group id of core: org.hibernate.ogm
* Keep the same license we use in OGM
* Create a repository per dialect: each repository will have it's own
life-cycle, it will depend on core and it won't impact the other
I'm not sure if I like the idea to have a repository per dialect in
term of maintenance but it seems the most flexible approach.
Would that work for everybody?
