Support cassandra-3.11.3

[kgreav]

Hi,

Now that 3.11.3 is released I've forked and updated the poms to point to the 3.11.3 cassandra-all dependency. Everything builds fine and I ran the tests and most of them succeeded successfully. Some tests failed but it looked like maybe it was a problem with my environment (nodes were unresponsive/overloaded or something). Couldn't find much documentation on tests so didn't investigate too deeply but everything seems to be working as intended.

Anyway, I'd put in a PR but the branching strategy doesn't really allow for it, so I'll just link to my branch here: https://github.com/kgreav/cassandra-lucene-index/tree/branch-3.11.3

Can we get this merged into a new branch?

I'd be happy to help with verification to do an actual release as well if that's what it takes, and same for 3.0.17 (although doesn't seem there is as much demand for 3.0). Will put everything in PR's if you can create a branch that I can use as a base (3.11/3.0 maybe?)

Cheers,
Kurt
