ClusterManager: Implements support of remote clusters.
After this change users will be able to:
* Create cluster and add/remove servers to it
* Install apps on remote cluster
* Move already installed apps between clusters
* Apps running on server being removed will auto-migrate
to another server from that same cluster
This is achieved by:
* Installing and running minimal version of dodo on remote cluster
* Ingress-nginx is installed automatically on new clusters
* Next to nginx we run VPN client in the same pod, so that
default cluster can establish secure communication with it
* Multiple reverse proxies are configured to get to the
remote cluster service from ingress installed on default cluster.
Next steps:
* Support remote clusters in dodo apps (prototype ready)
* Clean up old cluster when moving app to the new one. Currently
old cluster keeps running app pods even though no ingress can
reach it anymore.
