Todays Task: Make Pods immutable

1. Create Pod holiday with two containers c1 and c2 of image bash:5.1.0, ensure the containers keep running
2. Create Deployment snow of image nginx:1.19.6 with 3 replicas
3. Force container c2 of Pod holiday to run immutable: no files can be changed during runtime
4. Make sure the container of Deployment snow will run immutable. Then make necessary paths writable for Nginx to work.
5. Verify everything
