k8s deployment docs
updated k8s deployment docs. would love to hear thoughts / feedback.
todo: the link to daemon docs + some daemon descriptions still need to be filled in. given the change from enabled -> enums, some of the commands will need to be updated
Test Plan: went through both deployment guides (and fixed the issues that i ran into). if this looks good, next step is to add tests for the deployment guide.
