Allow adding labels to routes

[xstefank]

Describe the bug

We have only annotations now:

quarkus.openshift.route.annotations."test"=value

And I need label for my use case.

Expected behavior

There is something like:

quarkus.openshift.route.labels."test"=value

Actual behavior

It's not possible to configure label just for the route.
