Unhandled exception when "None" is passed in as new_size to extend

[John Griffith]

Currently the extend method in the cinder volume_actions extension checks for KeyError and ValueError, however the negative tests in Tempest include passing None in to the new_size which results in an unhandled trace in the test logs.

Add TypeError to the list of exceptions we look for.

    Catch TypeError when new_size is None on extend

    The volume_actions extend method does not catch/handle TypeError
    exceptions. The tempest volume_actions test includes a negative
    test that doesn't pass in a new-size so the result is we get an
    unhandled exception/trace in the log files for these runs.
