[omdb] Add db vmm list and db vmm info (#6936)

`omdb db` has commands for listing and displaying details regarding
customer VM instances. These commands reference the Propolis VMM
processes whose states are recorded in the `vmm` table, including their
IDs. However, there are no commands for directly querying that table,
which is unfortunate. While debugging an issue on the colo rack last
week, @augustuswm and I wanted to be able to list all VMMs in the
`Failed` state, but the only way to do this was to find a CockroachDB
zone and run our own manual SQL queries. Debugging this type of issue
would be easier if there were OMDB commands for querying the VMM table.

This commit adds two new commands to OMDB, `omdb db vmm list` (aliases
`db vmm ls`, `db vmms`), which lists entries from the `vmm` table
(potentially filtered by state), and `omdb db vmm info` (alias
`db vmm show`), which looks up a VMM record by UUID and displays its
contents. In addition, I factored out some code for displaying VMM
records
that was shared between the `db vmm info` command and the
`db instance info` command.

Closes #6928
