tested with master of unifiedpush-server, login/logout/account management works as expected

Let's wait a bit before merging this: http://lists.jboss.org/pipermail/aerogear-dev/2014-October/009368.html

What about add it in 0.2.8? I did not press the button yet.

[danielpassos]

I'm including it on 0.2.8 release

@matzew @lfryc @danielpassos in theory it shouldn't exist here, once it was already added on UPS https://github.com/aerogear/aerogear-unifiedpush-server/pull/403/files#diff-600376dffeb79835ede4a0b285078036L228

@abstractj see here:
aerogear/aerogear-unifiedpush-server#401

once the parent, containing 1.0.2 KC reference is released, on UPS a new PR similar to aerogear/aerogear-unifiedpush-server#401 should be issued, using the latest parent version.

In the past we agreed on doing the override on the UPS, instead of consuming KC from parent, since we had a lot of KC releases.

Since that now has settled, IMO it's time to go back to the parent based model, where we consume the KC version from, similar to other libraries defined in the parent pom.
