Summary:
Ref T9252. Leases currently have a `resourceID`, but this is a bit nonstandard and generally less flexible than giving them a `resourcePHID`.
In particular, a `resourcePHID` is easier to use when rendering interfaces, since you can get handles out of a PHID.
Add a PHID column, copy over all the PHIDs that correspond to existing IDs, then drop the ID column.
Test Plan:
- Browsed web UIs.
- Inspected database during/after migration.
- Grepped for `resourceID`.
- Allocated a new lease with `bin/drydock lease`.
