Pierre Riteau 00760ae25b Prevent leases from being deleted during event execution

A user can request to delete a lease while it is changing state via
event execution, which can trigger an error condition as on_end will
attempt to delete the corresponding aggregate.

This commit prevents a lease from being deleted while its start_lease or
end_lease events are in progress.

     Blazar now prevents leases from being deleted while their start_lease or
     end_lease events are in progress, to avoid concurrently accessing shared
     objects. For more details, see `bug 1791741
