Format servicedeployer.go

servicedeployer.go is growing as we add new features and functionalities in whisk deploy. It has core logic for deployment and undeployment. Please create two separate go files, one for deployment and one for undeployment.

Start by reading servicedeployer.go and identify the existing deployment and undeployment logic and their shared dependencies. Split the two responsibilities into separate Go files while preserving current whisk deploy behavior, then verify both deployment and undeployment flows still work.
