Support pagination for volume list

Since v2 api supports pagination, we should add this support in
cinderclient too.

Avoid extra lookups in extra-specs-list

extra-specs-list used to use the extra-specs cinder extension
to get information on volume type extra specs. This information
is publicly available through the volume-type API [1] thus we
can avoid the extra-lookups of querying the extra-specs extension.

As the extra-spec info is publicly available, remove the part of
the docstring of cinder extra-specs-list that says 'admin only'.

Fix order of arguments in assertEqual

Some tests used incorrect order assertEqual(observed, expected).

The correct order expected by testtools is...

    def assertEqual(self, expected, observed, message=''):
        """Assert that 'expected' is equal to 'observed'.

        :param expected: The expected value.
        :param observed: The observed value.
        :param message: An optional message to include in the error.
        """

The string length of the sum of the results of repr(expected) and
repr(observed) is greater than 70, then, MismatchError message is
changed, as below.

  Ex.:
        raise mismatch_error
    MismatchError: !=:
    reference = '_123456789_123456789_bar'
    actual    = '_123456789_123456789_123456789_123456789_123456789'

Use adapter from keystoneclient

The keystoneclient provides an adapter which maintains the client state
around the session. We should re-use this rather than copy it and it
also means we will get new adapter functions and parameters as they
become available.
