1. Adding the ability to create an interactive cluster with head node to be part of the remote cluster instead of the compute instance. This is now the default option. With this, the library can be used with VSCode for interactive mode. If you want to switch to CI as head node, specify ci_is_head=True in getRay()
2. Upgrade to ray 1.9.1 to fix log4j vulnerability issue
3. Remove unnecessary dependencies from default base conda and pip installation
