feat: add base kubernetes manifests (#5664)

Adds bare minimum, base kubernetes manifests for running erigon in
kubernetes.

Does not include crucial beacon chain, persistent volumes, etc.

I currently use this as a base for 5 erigon Pods, each with an erigon
execution node and prysm beacon node, along with 10 rpcdaemon pods, a
TLS-terminated Ingress with a cert-manager issued TLS certificate. I
would like to give back to the community then use this as an upstream
kustomized base. See: https://kustomize.io
