Specify a lower restart delay for swarm integration tests 

If no restart delay is specified for a swarm service, the default
restart delay is 5 seconds. This is a reasonable value for actual
deployments - one example of where it's useful is that if a bad image is
specified, the orchestrator will wait 5 seconds between attempts to
restart it instead of restarting it in a tight loop.

In integration tests, this 5 second delay is dead time. The tests run
faster if the delay is reduced. Set it to 100 ms to avoid the waste of
time.

This appears to speed up a few tests:

DockerSwarmSuite.TestApiSwarmForceNewCluster 37.241s -> 34.323s
DockerSwarmSuite.TestApiSwarmRestartCluster  22.038s -> 15.545s
DockerSwarmSuite.TestApiSwarmServicesMultipleAgents 24.456s -> 19.853s
DockerSwarmSuite.TestApiSwarmServicesStateReporting 19.240s -> 10.049s

...a small step towards making the Swarm integration tests run in a
reasonable amount of time.

Also, change the update delay for the rolling update test from 8 seconds
to 4 seconds, which should be sufficient to differentiate between
batches of updated tasks. This reduces the runtime for
DockerSwarmSuite.TestApiSwarmServicesUpdate from 28s to 20s.
