[infra] Local Cluster (failed)

[bhongy]

Same as #2 but do a squash merge

A failed first attempt to bootstrap local k8s cluster to support dev environment

Issues:

• pod frequently stuck and could not be terminated, causing worker node to stuck and unable to be terminated as well
• vscode remote does not support "attach" to k8s pod, k8s vscode extension has support for attaching but no support for vscode remote container config that'll properly init devcontainer
• failed to enable ssh access to pod in an automated fashion (for any new pod created), need to create user and register ssh key from local machine somehow, also concerned about security (open ssh access to k8s cluster rather than using kubectl)
