epriestley 89b37f0357 Make various Drydock improvements
Summary:
Tightens up a bunch of stuff:

  - In `drydock lease`, pull and print logs so the user can see what's happening.
  - Remove `DrydockAllocator`, which was a dumb class that did nothing. Move the tiny amount of logic it held directly to `DrydockLease`.
  - Move `resourceType` from worker task metadata directly to `DrydockLease`. Other things (like the web UI) can be more informative with this information available.
  - Pass leases to `allocateResource()`. We always allocate in response to a lease activation request, and the lease often has vital information. This also allows us to associate logs with leases correctly.

Test Plan: Ran `drydock lease --type host` and saw it perform a host allocation in EC2.
