    Handle downgraded client for snapshot-create

    When a CLI user specifies --os-volume api-version 3.66, the shell
    will execute the appropriate shell code, but if the server only
    supports < 3.66, the client is automatically downgraded and correctly
    uses the pre-3.66 SnapshotManager.create() method.

    In that case, the 'force' parameter, which is technically not allowed
    in mv 3.66 (but which silently accepts a True value for backward
    compatibility), will have a value of None, which the pre-3.66 code
    happily passes to cinder as '"force": null' in the request body, and
    which then fails the Block Storage API request-schema check.

    Handle this situation by detecting a None 'force' value and setting
    it to its pre-3.66 default value of False.
