Description:
value field in mysql.inventory table is too short to handle certain data. For example fingerprint from "Reflection for Secure IT" which uses longer fingerprint IDs than OpenSSH.

How to repeat:
Attempt to use a key from Reflection, get error message that string is too long, agent won't start.

Suggested fix:
Currently it's varchar(64), it could be varchar(10000) as that's the limit at the Dashboard side.

This isn't actually fixed quickly. The contents of this value are later used as a *component* of a name in the repository, which currently is 255 characters itself. Changing this would require a migration (well at least a potentially expensive ALTER TABLE).

We should document this as a limitation, as the upgrade implications are too great at the moment. 

Document the limitation, and the work around - use --agent-host-id within the mysql-monitor-agent.ini file so that a shorter unique id can be hard coded.

I've added this as a known limitation to the new reference appendix.
