[CE-386][CE-387]Refactor code to reduce duplicate code

Fabric peer creates chaincode container using docker
in docker method. This create challenges while
docker endpoint in k8s cluster is unknown. In this
patch set, a k8s daemon set is introduced to start
up a DINK pod on each k8s node to make sure that
the VM endpoint is available. This patch set also
remove a lot of duplicate code.
