Revert "Remove requireChangeId."

This reverts

* commit ec79eb968296c5900b483c87439901a3ce8862df (I2c407bdded0,
  "Remove requireChangeId.")

* commit 80beb1cac22c5e1607c6235dc6f85ecd86d21327 (I409106ce "Remove
  fields/methods that are unused since requireChangeId has been
  removed")

Reason for revert: This uncovered internal users at Google.

In particular, PutMessage, which is a commonly used REST API endpoint,
requires a Change-Id to be included if requireChangeId=false.

Change-Id: I626dbb4d53fbcbf5983b0a5e79ceadbee8a42db9
