Remove minimum lease length. Expiration must just be greater than current time.

Fix query for setting an attribute.

Found these while unit testing.  Almost done.

And fix function prototype in Quota module.

And some minor updates to the Quota module.

New quota object module for wrapping project quota database state.  Derived
from the Lease object, but simpler (no locking, no attributes, no permissions).

Lease module has been updated to fix some typos, and a couple of minor
issues and omissions.

Add permissions (add, revoke, check) and locking functions for leases.  Similar
to what we do for images.

Initial check-in of a perl module representing persistent leases.  Mostly

chain in the DB, which causes the samecert check to fail oon
pre-existing slices.

the nodecheck to run in MFS even if not in the reloading state.

yet another new update.

We put the lease in this state while allocating the storage associated
with a dataset lease.

Upstream pulled in a patch to include this, so we no longer need

different place in the webhook data than I did.
