Added very basic Ansible setup to run the shard report.

This currently relies on having pre-sent the Index Verifier output to the hosts ahead of time,
but eventually this script will automatically scan a period of time of all deleted tasks from the DB.
Added new hosts for the other instances
Added a playbook for setting up the remote hosts with the (prebuilt) tool binaries
Automatically transfer the Index Verifier email attachments (previously saved to a default location) out to the remote hosts to be used as input.

Ensure the Shard Report information is displayed to the operator
Updated README.md with Ansible information, and added in the autofixshards play (which I thought I had..)
