Have eventlet monkeypatch the time module
Have eventlet monkeypatch the time module

Without this, mongod retry logic in the various services started as
commands fails to behave as expected and does not reconnect as soon as
the mongod service has returned to availability.

In addition to the mongod sleep there are two other time.sleep calls
that may be reached by this change. Review and discussion with others
indicates that their behavior will continue to be correct with the
monkeypatch in place.
