Description

It would be nice to make the caching implementation configurable. ACCUMULO-4177 introduced a new cache type. Instead of Accumulo having a list of built in cache implementations, it could have a configuration property for specifying a block cache factory class. Accumulo could ship with multiple implementations of this as it does after 4177 and allow users to easily experiment with implementations that Accumulo did not ship with.

It would be nice to have ACCUMULO-3384, so that these custom cache impls could use that for custom config.
