Brand new SPQR 1.1.0

[Denchick]

Hi! The SPQR development team is here and we are proud to announce the new version of SPQR 1.1.0! Let's see what has changed.

PostgreSQL JDBC Driver
Right now we are working on making the popular PostgreSQL Java driver compatible with SPQR. We support new SQL queries and improve support for prepared statements.

Sharing using hash functions
When creating sharding rules, we added the ability to specify which hash function to use. There are 3 options available right now: ident (identity), murmur hash and city hash.

Other
We continue to work on the stability of our solution, so we are improving our tests and writing new ones. We add drivers tests. The full list of changes can be found in the release notes.
