Bryan Neumann 7e38339201 Dell EMC: PowerMax - Configurable SRDF snapshots
Add volume type extra spec boolean property
'powermax:disable_protected_snap'. Enabled when set to: `'<is> True'`,
`'True'`, `'true'`, or True, otherwise the property is disabled by
default.

When set to True, snapshot won't be replicated and won't
match the source volume type, it will be a regular device
no matter what.

If the property is not enabled in the volume type extra_specs, then
there is no change from the current behavior.

Implements blueprint powermax-protected-snap-config

Dell EMC PowerMax driver: Added SRDF ``powermax:disable_protected_snap``
volume-type extra-spec property for the purpose of avoiding
overconsumption on both source and target storage arrays.
An operator may enable this functionality by creating a specific volume
type with the property::
"powermax:disable_protected_snap": "<is> True"
When disabled (which is the default and current behavior), a
replicated source volume will be protected with a snapshot of the
same volume type.
When enabled, snapshots of replicated source volumes will be treated
as regular, non-replicated devices.
