Add comments to the conversion_hosts table

[djberg96]

In my continuing effort to understand things better by documenting them, this is my attempt to document the conversion_hosts table.

One question arose which is what is the effective difference between max_concurrent_tasks and concurrent_transformation_limit.

Feedback and suggestions welcome.

Can you add a test that fails when any new columns are added to the table and they don't have comments?

[djberg96]

@bdunne I wouldn't know how to enforce it. I think that would require some sort of core migration change, wouldn't it?

@djberg96 https://github.com/djberg96/manageiq-schema/pull/1 Let me know what you think

@bdunne Didn't know about automated review. Looks good, merged it, thanks.
