Extension <> CLI Interface

[aviramha]

Make the extensions use the CLI.

1. CLI will provide targetable pods/deployments, instead of having it implemented separately in each extension.
2. It will pass command line arguments and environment variables passed on command line to the process. This should resolve Passing cli arguments from pod to local application #772 .
3. It will create the agent for the process, which will let us pass environment variables to it from the outside. This will fix Go's Env vars don't work on macos M1, go version go1.18.4 darwin/arm64 #373 because we can remove the code that sets env from inside the process
