Add Sector blocklist

[n8maninger]

Add the ability for hosts to block sectors by root, preventing them from being stored.

This change would add a new table, 4 new methods on the volume manager, and 4 new endpoints.

persist/sqlite changes

• Add a new table to init.sql
• Add a migration to create the table on existing hosts to migrations.go
• Add methods for add, list, and remove to Store

host/storage changes

• Add methods from the sqlite store to the Store interface in persist.go
• Add methods for add, list, and remove to VolumeManager.
• Keep the blocklist in memory for speed. Load it at startup.
• Check if the sector root is blocked in VolumeManager.Write and return an error.

api changes

• Add endpoints to the API for add, list, and remove. Maybe under /sectors/blocklist

@n8maninger I'd like to try to get this feature implemented. Looks a little involved so I may be asking some questions!
