Refactor cloud-init support and VM Salt config seeding
Missing package dependancies added.
A missing "config" parameter for qemu-nbd based seeding
method added.
A new seeding method utilising Cloud-init added.
The qemu-nbd based method is still a default method
for backward compatibility.
To enable cloud-init, set the "seed" parameter on
a cluster or node level to "cloud-init".
To disable seeding, set this parameter to "false".
Setting this parameter to "true" will default to
the "qemu-nbd" method.
Salt Minion config file will be created automatically
and may be overrided via cluster or node level
metadata:
salt:
control:
cluster:
mycluster:
seed: cloud-init
cloud_init:
user_data:
salt_minion:
conf:
master: 10.1.1.1
or for qemu-nbd case:
salt:
control:
cluster:
mycluster:
seed: true
config:
host: 10.1.1.1
That may be useful when Salt Master has two IPs in
different networks and one of the networks isn't accessible
from a VM at the moment it's created. Setting a reachable
Salt master IP from metadata helps avoid potential problems.
Also, a liitle optimization has been done to parse/dump
an libvirt XML only once while modifying it.
