[Bug 1233831] [NEW] maas doesn't return zookeeper instances for newly provision environment

[Peter Petrakis]

Public bug reported:

The problem:
I can clearly see that a machine is allocated in response to the bootstrap request and that the
same machine is destroyed when the env is trashed, yet, I can't get a handle on the environment.

Odd thing is this problem cropped up all of a sudden. I've been provisioning via juju
maybe 5-6 times a day due to the hardware speed over the last week and it just stops working.
I've tried restart the processes, upgrading to latest maas, and rebooting. It just stays in this
state. I can't use it for anything.

tcpdump (see attached) shows that nothing is being returned in response to the

To compare, I traced my other maas, it should be returning something
like this.
