[2.5, enhacement] MAAS should, by default, create virtual machines inside a KVM host /pod based on a prefix

[Andres Rodriguez]

[2.5] MAAS should, by default, create virtual machines inside a KVM host /pod based on a prefix. This prefix could be the KVM host name, otherwise, it could be nice to allow the user to override the prefix.

For example, when juju creates containers inside a host, it does so in a stable naming convention, e.g:

juju-id-0
juju-id-1
juju-id-3

MAAS should do the same with KVM pods.

Nice idea! It might be a bit strange if we generate both names with petname; you'd end up with hosts like:

>>> import petname
>>> for i in range(10):
... print('-'.join([petname.generate(2, '-'), petname.generate(2, '-')]))
...
wise-feline-moral-moray
needed-ghoul-witty-tuna
united-crow-sharp-gecko
viable-viper-cuddly-bream
ideal-lizard-prompt-marmot
fleet-bunny-sound-kid
chief-toad-handy-ghoul
dear-corgi-light-zebra
moving-oryx-golden-heron
on-beetle-prompt-mole

We could use the the node_id or similar as the suffix, though that could eventually reach into the thousands if you bring up and tear down a lot of VMs. Or create a separate auto-increment per-pod. Or simply iterate until we find a good one... etc.

Names are hard.
