deprecate OpenCensusInputRowParser in favor of OpenCensusProtobufInpu…
…tFormat (#26) InputRowParsers have been deprecated in favor or InputFormat. This implements the InputFormat version of the OpenCensus Protobuf parser, and deprecates the existing InputRowParser implementation. - the existing InputRowParser behavior is unchanged. - the InputFormat behaves like the InputRowParser, except for the default resource prefix which now defaults to "resource." instead of empty. - both implementations internally delegate to OpenCensusProtobufReader, which is covered by the existing InputRowParser tests.
