[omdb] Add disks, historical VMMs to omdb db instance show (#6935)

Inspired in part by what would have been nice to have while @augustuswm and I were debugging failed instances on the colo rack a few days ago, this branch adds additional data to the `omdb db instance show` command. Now, we fetch and display a list of all disks attached to the instance: ```console root@oxz_switch1:~# /var/tmp/omdb-eliza-test-7 db instance show e97e9fb9-62c3-4745-9d91-b0b6fa2baeba note: database URL not specified.

This is useful for debugging instances which have migrated and/or been restarted --- it's often useful to figure out what has happened to VMMs that previously incarnated an instance, and determine their IDs and sled to find zone bundles etc. The list of past migrations is now enabled or disabled by the `--history` flag, as well. ```console root@oxz_switch1:~# /var/tmp/omdb-eliza-test-7 db instance show e97e9fb9-62c3-4745-9d91-b0b6fa2baeba --history note: database URL not specified.
