CLOUDSTACK-9504: System VMs on Managed StorageThis PR makes it easier to spin up system VMs
on managed storage.

Managed storage is when you have a dedicated volume on a SAN for a particular virtual disk
(making it easier to deliver QoS).

For example, with this PR, you'd likely have a single virtual disk for a system VM. On XenServer,
that virtual disk resides by itself in a storage repository (no other virtual disks share
this storage repository).

It was possible in the past to spin up system VMs that used managed storage, but this PR facilitates
the use case by making changes to the System Service Offering dialog (and by putting in some
parameter checks in the management server).

  Added support for system VMs to make use of managed storage

> There are three related items for this ticket:
> 1) Do not permit "custom IOPS" as a parameter when creating a system offering (throw
an exception if this parameter is passed in).
> 2) If you transition managed storage into maintenance mode and system VMs were running
on that managed storage, the host-side clustered file systems (SRs on XenServer) are not removed.
Remove them.
> 3) Add integration tests for system VMs with managed storage.
