WHY
A25 test is failing on private clusters.

WHAT
A25 test expects public route table being present which is not true for private clusters. Discovered on ROSA multiAZ private-link cluster

HOW
This has to be updated so that the +1 public route table is only expected for public clusters:
https://github.com/integr8ly/integreatly-operator/blob/master/test/functional/aws_standalone_vpc.go#L508-L509

Not sure if it is possible to see from within the test whether the cluster is private or public. Worst case we would need to introduce an env var and add this env var to test (and test container) when running the test(s).

Need to distinguish between a public and private cluster - differences in route table config might be an indication. May be alternative approaches. 

TESTS
N/A

DONE

• A25 passes on both public and private clusters
