Expose Drydock leases via Conduit

Summary:
See T13212 for some context and discussion on this being revived.
See T11694 for original context.

Add a query constraint for lease owners and implement the conduit search method for Drydock leases.

Ref T11694. Fixes T13212.

Test Plan:
- Called the API method from conduit and browsed lease queries from the UI.
- Used the new "ownerPHIDs" constraint via API console.
