[Feature]: airgap: OAPI access using a Net Access Point

[jfbus]

Problem to Solve

The VPC has no internet access.

A Net Access Point is required for the CCM and the CSI to be able to call OAPI.

Proposed Solution

The OscCluster spec has a new network.netAccessPoint.services attribute that is a list of services used by the workload cluster.

If internet is not disabled (see #645), netAccessPoint must not be set.

If internet is disabled, a netAccessPoint is always created. As the CCM is required, and as the CCM requires access to the api, services is automatically added to the list of services if missing.

Available services:

• api
• oos

A NetAccessPoint is created linking all node RouteTables to the selected services.
