Couchbase Spring Cache Connector

================================
Version: 2.1.0
Date:    2017-01-03

The 2.1.0 version brings the cache connector up
to Java SDK 2.3.6 as well as Spring 4.3. It also
addresses doc bugs around expiration and adds
proper methods for dealing with seconds-based
expiry (instead of ms).

Changelog between 2.0.0 and 2.1.0

      fix tests and update dependencies
      Provide ttl in seconds, fix MS to second conversion.
      Override get(Object, Callable) for 4.3.

      fix tests

Simon Baslé (3):
      readme on manager creation, bucket type limitation
      demonstrate both annotation and xml configuration in integration test
      prepare next version

This is the first release in the 2.0 branch.

Extracted from the initial implementation in Spring Data Couchbase v1.4.x, this release features:

 - Implementation of the Cache and CacheManager on top of SDK v2 (Bucket)
 - Cache storage now works well even in a shared Bucket (cache name is part of the Couchbase key).
 - Improvement of putIfAbsent atomicity.
 - Added basic integration tests.
 - Avoid error with clearing empty cache.
 - Prepare support of get(key, valueLoader) operation.
 - Rework manager construction and allow dynamic creation of Caches.
 - Allow to prepare additional caches before initial cache loading.
