Extend configuration support for Infinispan caches

The current implementation of the Oracle connector supports only embeddable ISPN caches but we would like to extend this support to work with a remote ISPN service as well as extend the configuration options for the caches accordingly.

As a high-level idea we would have:

• log.mining.buffer.infinispan.type=[embedded|remote]
• log.mining.buffer.infinispan.embedded.xxx=yyy
• log.mining.buffer.infinispan.remote.xxx=yyy

We would then also deprecate the existing log.mining.buffer.location property and add a new equivalent under the log.mining.infinispan.embedded namespace using the old property as a fallback.
