Upgrade to Spring Session Data MongoDB 2.0.0.RC2

[vpavic]

It would be nice if we could get master to build against snapshots in the meanwhile. This would also unblock #11055 and #11063.

@vpavic master now builds against the snapshots. Any news about the bom? Thanks!

[vpavic]

Thanks!

Regarding the BOM, we should get @rwinch into discussion on that topic.

Renaming to track the RC2 - see #11082 (comment).
