    Fix storage.hbase.util.prepare_key() for 32-bits system

    storage.hbase.utils.timestamp() will return long type object on 32-bits
    system, which will cause exception in ceilometer/alarm/storage/impl_hbase.py:
    'long' object has no attribute 'encode'.
    Then developers on 32-bits system will never get local test passed.

    This patch changes type check in prepare_keys() from int to six.integer_types,
    which will work for both 32-bits and 64-bits system, python2 and python3
    environment.

    Note: no test code is added, because jenkins runs on 64-bits system. Reviewers
    can download code and verify it on 32-bits system.
