killing old dead controllers

[Daniel Bidwell]

I have a machine with 2 dead controllers that I can't figure out how to
delete.  A "juju controllers" produces the following:

root at juju:~# juju controllers
Use --refresh flag with this command to see the latest information.

Controller  Model    User   Access     Cloud/Region         Models  Machines    HA  Version
lxd-test    -        admin  superuser  lxd/localhost             2         1  none  2.0.2  
test-lxd*   default  admin  superuser  localhost/localhost       2         1  none  2.1.3

lxc list produces:

root at juju:~# lxc list
+------+-------+------+------+------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+------+-------+------+------+------+-----------+

Any attemtp to remove, delete, kill, or destroy results in the command
hanging and never coming back.  I have been trying to develop some
local charms using lxd.  I know that this kind of testing and
developemnt is hard on vms/containers, but throwing away the vm and
reinstalling ubuntu is probably not the desired behaviour.
