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.

Spawning AArch64 VMs using salt.control.virt requires a few extra
domain configuration items to be configurable:
- libvirt xml: pass loader param to vm
  Based on upstream commit [1].
- libvirt xml: pass virt machine type
- libvirt xml: pass cpu mode to vm
- virt module: Allow NVRAM unlinking on DOM undefine
  UEFI-enabled VMs usually have pflash (NVRAM) devices attached,
  which require one additional libvirt flag to be passed at 'undefine'.
  This is usually the case for AArch64 (arm64) VMs, where AAVMF (AA64
  UEFI) is the only supported guest bootloader.

[Fix] Doc

Issue: - It is not possible to pass [R]andom [N]umber [G]enerator
         device to libvirt guest xml in order to control entropy.

       - Doc has no information on how to provision vms using salt

Solution: - Pass rng parameters via kwargs from node: pillar
            Attach rng xml object to generated xml.

          - Provide with an example

salt-minion started via upstart is not using /etc/environment to
source variables therefore is not using system wide http_proxy parameters if
they are set there. With this patch if salt.minion.env_vars is set to engine:
file salt will set envvars in /etc/default/salt-minion and will use them for
all commands executed remotely via salt. Since /etc/default is not used on
systems with systemd override for salt-minion to use /etc/environmnet will be
set.

Exposing CA keys in a mine creates a security flaw, thus such
should be avoided.
This change removes code responsible for putting and retrieving
CA key from a mine and changes the ca.sls state to allow configuring
where CA cert and its key would be generated as well as their owners.
