Create disk schema per machine via maas/client.sls with default lvm schema + default values

NOTE: This should be used mostly for custom root partitioning and RAID configuration. For not-root partitions please use salt-formulas/salt-formula-linux.

Raid + LVM setup, 2xSSD + 2xHDD


Note: This setup lacks the ability run state twice, as of now when "disk_partition_present" is called, it tries blindly to
delete the partition and then recreated. That fails as maas rejects remove partition used in RAID/LVM.

Test pillars
==============

Mind the postgresql and rsyslog `.sls`. Database and syslog service are required for MAAS to properly install and work.

* https://github.com/salt-formulas/salt-formula-rsyslog/tree/master/tests/pillar


Module function's example:
==========================

* Wait for status of selected machine's:

.. code-block:: bash

    > cat maas/machines/wait_for_machines_ready.sls

    ...
