Reduce HTTP check internal to 1s in Docker tests

When testing the reaction of the Gerrit HA setup to unhealthiness, it is
important that the incoming calls will be promptly redirected to the
healthy node.

The old delay of 10s and three consecutive check failures was bringing
the whole HA cluster to be unhealthy for 30s, which is quite unpleasant
user experience.
