Description

Docs - include details on Accumulo VFS classloading

Andrew Hulbert came up with a really great guide on the wiki here: https://geomesa.atlassian.net/wiki/spaces/GEOMESA/pages/502661122/GeoMesa+Accumulo+Distributed+Runtime+Tips
He also figured out that setting https://accumulo.apache.org/1.9/accumulo_user_manual.html#_general_vfs_cache_dir can be pretty important as the OS may wipe out the default location under /tmp, causing classloading issues.

We should document and/or link to these in the official docs.

Emilio Lahr-Vivaz I’m going to toss this into the 3.0.0 fix version so that we try and look at this for the release.
