Two fixes in grpc.framework.core._end

Do not include internal proto header

Replace metadata objects with a Metadata class

(1) Move metadata and details constants for gRPC-on-the-wire tests into
grpc.test_common.

(2) Drop definitions of setUpModule and tearDownModule from a unit test
module that, because it uses the load_tests protocol, never had those
methods called anyway. :-(

Check for allowed characters in metadata key.

Outlaw comma in non-binary metadata values

(1) Call "cancel" on each future, not on the list of futures.

(2) If and when futures mature their actions should simply abort all
outstanding operations and cancel any other futures. They should not
shut down the _End's internal thread pool; only the termination action
of the last operation to terminate should shut down the pool (in the
case of their having been active operations at the time at which the
_End's stop(grace) method was called).
