  to 4f8da435baca8264a0893ec35598ab727efcf04a
  - Merge "Fix compare volume stats for storage_protocols"
  - Fix compare volume stats for storage_protocols
    
    The change [1] added to scheduler a list of
    storage_protocols upon reception of the stats from
    volume. Scheduler can handle a list of storage
    protocol variants for NFS, NVMeOF, iSCSI and FC.
    
    The test_backends_capabilities compare volume
    stats from list_pools and
    show_backend_capabilities without check if the
    procotols are in the list. Once change [1]
    standardized some storage_protocols
    with a default value, list_pools will show the
    standard protocol defined by the position zero
    from the list, and show_backend_capabilities
    will return the protocol defined by user as
    backend. Even if, the protocol returned by
    show_backend_capabilities are in the list of
    allowed protocols the test will fail if this
    protocol is not equal the default position
    zero from the list.
    
    This patch provide a check if
    show_backend_capabilities returns
    valid storage_protocols using the list of allowed
    variants and set the preferred protocol to it.
    
    This fix is needed for third-party CI systems that
    may not be running tempest in a greenfield
    environment. So while cinder change [2] fixed
    drivers to report the canonical storage protocol
    name, we can't assume that the drivers being
    tested contain that fix.
