    Standardize timestamp fields of ceilometer API

    For currently, the timestamp in query fields is not unified, this
    patch standardizes the usage of timestamp query fileds:

    - unify the time query filed in API to *timestamp* supported only.
    - unify the time related fileds of filters to start_timestamp and
      end_timestamp to simplify the process logic.
    - improve the _query_to_kwargs method to give explicit presentation
      if user specifies unsupported query fields.
