silvacarloss 04a3db2f9a Share server migration enhancements

A series of enhancements can be performed in the share server
migration operation, and share backends might support
nondisruptive share server migrations, which was not covered
in the previous approach.

-  Skip the destination share server network allocation if the
driver is capable of reusing the source share server allocation.
Manila will switch the allocations in the migration complete phase.

- Allow share backends to reuse the share servers in case they
are able to do so in a share server migration scenario.

- Nondisruptive migration is now feasible depending on whether the
share driver supports it and if the share network parameters have
not changed.

- Share servers will be always deleted whe the share server
migration complete operation is finished.

     Added share server migration enhancements. Share back ends that support
     non-disruptive migration are able to do so, in case no network changes
     were identified and if the back end driver supports reusing ip addresses.
