Etcd slaves smart start

Registered by Alexander Tivelkov

Currently the etcd services do sleeps/delays on their start to prevent possibility of concurrent initialization.
This prevents split brain conditions, but is ugly and reduces deployment performance.

This should be optimized, so the services probe the status of etcd cluster before proceeding instead of simple unconditional waiting.
