[Pure Storage] Replication failover issue

[Simon Dodsley]

A patch[1] removed a specific REST version call that is required to get the correct list of snapshots to recover when doing an async replication failover.
This means that a replication failover will not correctly copy replicated volumes to the failover device.
The specific function affected is `_async_failover_host()`

Fix needs to be backport all the way to stable/yoga

    [Pure Storage] Fix failure in replication failover

    A previous patch incorrectly removed a call using a specific
    version of API as part of the replication failover process.

    The call being made to the backend fails as one of the
    parameters is not supported in later API version.

    This patch fixes the call to the backend to use the required
    API version.

    There are no tempest tests for replication failover, hence
    why the original patch passed tests.
