Users can't create private routes by default

[rustyjux]

By default, users can't create private routes (where route hosts end in .cluster.local which creates a route .svc.cluster.local). As is, it is necessary to go into keycloak authz and add .svc.cluster.local to perm-domains.

The issue likely lies in validate_hosts() here -

gwa-api/microservices/gatewayApi/v1/routes/gateway.py

Line 538 in 0e2ff4d

def validate_hosts(yaml, reserved_hosts, ns_attributes):

Resolution could include adding .svc.cluster.local to the default list of allowed_domains or otherwise modifying the function logic.

I have a note from a conversation with Aidan that the issue may be a misplaced if statement (should be else) following the if statement checking if it’s a valid local route, but I'm not soo sure about this.
