  • In our on going saga to debug gremlins in outliers timeouts, we've noticed that sometimes we get timeout errors from the connection pool that are due to contexts being already expired when they get to the pool.
  • This PR adds a new error that distinguishes between actual timeouts from the
    pool and errors due to contexts being already expired by the time it gets to
    the pool.
