[cmd/opampsupervisor]: Configure the ppid option in the opamp extension

[BinaryFissionGames]

Description:

• Configures the PPID of the opamp extension in the supervisor. This allows the collector to detect if the supervisor exits and shut itself down.

Link to tracking Issue: Closes #32189

Testing:

• Manually tested by starting the supervisor, then kill -9'ing the supervisor. The collector previously would have still been running, but now shuts itself down. Doing this you can also see the following log:

2024-05-06T14:52:31.010-0400	error	[email protected]/collector.go:278	Asynchronous error received, terminating process	{"error": "collector was orphaned, process with pid 38908 does not exist"}

Documentation:
Added orphan_detection_interval to the spec as a configurable option
