[cli] "langstream run docker" command: start the webservices and other improvements

[eolivelli]

Summary:

• Now with the "langstream run docker" command the container runs also the Gateway API service and the Control Plane service
• This way when you run the application locally you can have almost the same user experience as while running on K8S or on a cloud provider
• Now you can also customise the "docker run" command by setting the name of the "docker" CLI command (--docker-command), resource requests (--memory, --cpus) and also you can pass additional arguments (--docker-additional-args)
• You can also now filter your application and run only one "agent" (actually and "executor") with the "--only-agent" option

Changes:

• build the jar artifact for the gateway and the webservice project
• implement the things above
• reduce some logging (we are printing too much on the logs, especially secrets)
