[3/5] mesos git commit: Drop `404 NotFound` responses in the executor library.

[vi...@apache.org]

Drop `404 NotFound` responses in the executor library.

Previously, we did not use to drop `404 NotFound` responses in the library and
send `Event::Error` to executor. However, this can be trigerred upon an agent
restart when it has not yet set up HTTP routes.
