Add request header annotation and resource-id fields (#728)

_**READ BEFORE MERGING:** All PRs require approval by both Server AND
SDK teams before merging! This is why the number of required approvals
is "2" and not "1"--two reviewers from the same team is NOT sufficient.
If your PR is not approved by someone in BOTH teams, it may be summarily
reverted._

<!-- Describe what has changed in this PR -->
Adding a proto annotation to be used for automatically propagating
message fields into headers. Will be accompanied by SDK changes to
generate code for doing so based on the annotations. See
#236 and
temporalio/sdk-go#2226 for example.

Also adds additional `resource-id` fields to a number of messages for
use in routing.
