Trying to recycle connections
Launch working for usb deployment and started _DeployTarget class
IP deploy + launch.  Not working with same connection

Trying to keep connection all inline
Using old connection and doing all launch inline.  Pushing unification until later.

Removed prints & line breaks
Review fixes
Encapsulated / unified timeouts and set to 30 secs instead of 5 mins.
