[FAB-4435] gulp test recreates containers

This patch adds a "docker-ready" task to make sure that necessary
containers are recreated and up before the "test" task.

The "docker-clean" task now calls "docker-compose" to delete containers,
and "docker-ready" task depends on the "docker-clean" task, and then calls
"docker-compose" to create containers.  The "test" task depends on
"docker-ready" task so that the containers are recreated and ready before
each test run.
