  "message": "Introduce E2E fetch REST-API metrics\n\nThe E2E replication through the fetch REST-API\nneeds to be calculated from the client originating the call\nwhere the initial ref-update happens.\n\nIntroduce a new end_2_end metric to track this latency.\n\nWhen the pull replication is executed asynchronously,\nthe client originating the call propagates the timestamp\nin an HTTP header (X-StartTimeNanos) and propagated\nto the receiver side, which will use the initial time for\nrecording the final E2E replication time at the receiver\nside.\n\nAlso add the pull-replication async integration tests\nthat were completely missing before: testing with async\nreplication is key for demonstrating that the E2E metrics\nare working as expected.\nConsequently, the TEST_REPLICATION_DELAY is reduced to\n1 second for preventing the whole test suite to fail\nfor timeout.\n\nTODO: Additional assertion on E2E metrics in sync and async\nmodes.\n\nChange-Id: Ieb29e3475dc0938fe7700007b7d05a630c3c927f\n",
