Console operator should be building up a set of cluster nodes OS types, which he should supply to console, so it renders only operators that could be installed on the cluster.

This will be needed when we will support different OS types on the cluster.

We need to scan through the compute nodes and build a set of supported OS from those. Each node on the cluster has a label for its operating system: e.g. kubernetes.io/os=linux,

AC:

1. Implement logic in the console repo
   1. Add additional flag
   2. populate the supported OS types into SERVER_FLAGS
   3. update the filtering logic in the operator hub
