Post 5.0.0-alpha

[Josh Elser]

Hiya,

Thanks to everyone who helped get 5.0.0-alpha out the door. A few 
book-keeping things:

* I've updated JIRA, nuking the 5.x and 5.0 fixVersions, renaming 5.0.0 
to 5.0.0-alpha, and renaming 5.1.0 to 5.0.0. 5.0.0 is the fixVersion you 
want.
* Announcement has been sent out and I think I've cleaned everything 
else up.
* 5.x-HBase-2.0 is open for your commits (with a Maven version of 
5.0.0-SNAPSHOT)
* Rajeshbabu is going to look at making sure the 5.x branch is synced up 
with the rest of the changes from 4.x which might have been skipped in 
PHOENIX-4610.
* I'll continue to monitor the 5.0.0 fixVersion, trying to keep us on a 
trajectory to make that release happen sooner than later.
