    Add encryption-type-update to cinderclient

    This modification adds support for updating volume encryption types. The
    encryption-type-update command requires a single argument, the name or
    ID of the volume type whose associated encryption type should be
    updated, and up to four optional arguments representing new values for
    the encryption type attributes. The update implementation supports three
    use cases:

    1. The user wants to specify new values for attributes of an
       encryption type.
       - include the attribute and its new value at invocation
    2. The user wants to preserve the values for attributes of an
       encryption type.
       - exclude the attribute at invocation
    3. The user wants to set the values for attributes of an encryption
       type to provider defaults (only valid for cipher and key-size).
       - include the attribute but provide no value at invocation

    The encryption type may only be updated if the associated volume type is
    unused.

    This modification leverages update support for encryption types provided
    by the cinder volume encryption type API extension. See the following
    patch for more information:
