[FAB-2446] label fabric docker images

Enables filtering images and containers to find only
chaincode containers using the --filter option.

Added to fabric images:
 - org.hyperledger.fabric.version
 - org.hyperledger.fabric.base.version

Added to chain code images:
 - org.hyperledger.fabric.chaincode.id.name
 - org.hyperledger.fabric.chaincode.id.version
 - org.hyperledger.fabric.chaincode.type

Example:
  docker images \
	--filter label=org.hyperledger.fabric.version
