If a background job increments the totalTimeForEgressConnectionAcquiredToWireMicros metric and prints the corresponding log message after we have cleared the log but before we have gotten the initial metrics value here in egress_connection_acquisition_to_wire_metrics.js, then the test will not wait for the metric to actually be incremented by the intended command, causing the test to fail.

We can resolve this by clearing the log after the initial metric is obtained.
