[terraform] Deploy updated Identity and Tunnelbroker

Summary:
Published new Identity Service Docker image after lots of breaking changes to protos - see D10429

Also published Tunnelbroker due to changes in verifyUserAccessToken RPC which is called when establishing websocket session.

Test Plan: Tested both images on staging - they seem to work fine (accept requests, talk to each other via gRPC).
