Upgrade to Accumulo 3.x

[tb06904]

Describe the new feature you'd like
Accumulo 3.0.0 has been out a while and it is long over due that we look to upgrade to the latest version. This would mean breaking backwards compatibility with older versions of Accumulo due to the removal of deprecated methods and classes used in 1.x and 2.x.

To do this it would also need a Java 11 update for the code base (mostly done), there is probably scope to clean up lot of the code in the Accumulo store module so that we only target 3.x now.
