managed storage

@DaanHoogland I've been searching for comments from @rafaelweingartner, but
I don't see any regarding complexity.
I will say that 90% of this code exists in prior (private) branches that
customers of mine have been using throughout much of 2017.
Here are some videos that demonstrate a subset of the new functionality:
**KVM enhancements regarding managed storage:**

> Improvements for Managed Storage
> --------------------------------
>
> Key: CLOUDSTACK-9620
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9620
> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM, Management Server, VMware, XenServer
> Affects Versions: 4.11.0.0
> Environment: KVM, vSphere, and XenServer
> Reporter: Mike Tutkowski
> Assignee: Mike Tutkowski
> Fix For: 4.11.0.0
>
>
> Allowed zone-wide primary storage based on a custom plug-in to be added via
> the GUI in a KVM-only environment (previously this only worked for XenServer
> and VMware)
> Added support for root disks on managed storage with KVM
> Added support for volume snapshots with managed storage on KVM
> Enabled creating a template directly from a volume (i.e. without having to go
> through a volume snapshot) on KVM with managed storage
> Only allowed the resizing of a volume for managed storage on KVM if the
> volume in question is either not attached to a VM or is attached to a VM in
> the Stopped state
> Included support for Reinstall VM on KVM with managed storage
> Enabled offline migration on KVM from non-managed storage to managed storage
> and vice versa
> Included support for online storage migration on KVM with managed storage
> (NFS and Ceph to managed storage)
> Added support to download (extract) a managed-storage volume to a QCOW2 file
> When uploading a file from outside of CloudStack to CloudStack, set the min
> and max IOPS, if applicable.
> Included support for the KVM auto-convergence feature
> The compression flag was actually added in version 1.0.3 (1000003) as opposed
> to version 1.3.0 (1003000) (changed this to reflect the correct version)
> On KVM when using iSCSI-based managed storage, if the user shuts a VM down
> from the guest OS (as opposed to doing so from CloudStack), we need to pass
> to the KVM agent a list of applicable iSCSI volumes that need to be
> disconnected.
> Added a new Global Setting: kvm.storage.live.migration.wait
> For XenServer, added a check to enforce that only volumes from zone-wide
> managed storage can be storage motioned from a host in one cluster to a host
> in another cluster (cannot do so at the time being with volumes from
> cluster-scoped managed storage)
> Don’t allow Storage XenMotion on a VM that has any managed-storage volume
> with one or more snapshots.
> Enabled for managed storage with VMware: Template caching, create snapshot,
> delete snapshot, create volume from snapshot, and create template from
> snapshot
> Added an SIOC API plug-in to support VMware SIOC
> When starting a VM that uses managed storage in a cluster other than the one
> it last was running in, we need to remove the reference to the iSCSI volume
> from the original cluster.
> Added the ability to revert a volume to a snapshot
> Enabled cluster-scoped managed storage
> Added support for VMware dynamic discovery
