Added service name to dockerData struct.

Browse source 
In Swarm mode with with Docker Swarm’s Load Balancer disabled (traefik.backend.loadbalancer.swarm=false)
service name will be the name of the docker service and name will be the container task name
(e.g. whoami0.1).  When generating backend and fronted rules, we will use service name instead of name if a
rule is not provided.

Initialize dockerData.ServiceName to dockerData.Name to support non-swarm mode.
