* cmd/k8s-operator: generate static manifests from Helm charts
This is done to ensure that there is a single source of truth
for the operator kube manifests.
Also adds linux node selector to the static manifests as
this was added as a default to the Helm chart.
Static manifests can now be generated by running
`go generate tailscale.com/cmd/k8s-operator`.

plain k8s-operator should have hostinfo.App set to 'k8s-operator', operator with proxy should have it set to 'k8s-operator-proxy'. In proxy mode, we were setting the type after it had already been set to 'k8s-operator'

API v1 is compatible with helm v2 and v2 is not.
However, helm v2 (the Tiller deployment mechanism) was deprecated in 2020
and no-one should be using it anymore.

Users should delete proxies by deleting or modifying the k8s cluster resources
that they used to tell the operator to create they proxy. With this flow,
the tailscale operator will delete the associated device from the control.
However, in some cases users might have already deleted the device from the control manually.

* cmd/k8s-operator: users can configure operator to set firewall mode for proxies
Users can now pass PROXY_FIREWALL_MODE={nftables,auto,iptables} to operator to make it create ingress/egress proxies with that firewall mode
Also makes sure that if an invalid firewall mode gets configured, the operator will not start provisioning proxy resources, but will instead log an error and write an error event to the related Service.
