Foreign cluster resource: enforce peering type

[giorio94]

Description

This PR introduces an "immutable" PeeringType field as part of the ForeignCluster API, in order to explicit the type of peering and prevent switching from one to another, which would cause potential issues. This also enables a better UX through liqoctl.
