[CLOUD-3200] - querying k8s api to discover generated routes

[ricardozanini]

@luck3y this is the PR to fix https://issues.jboss.org/browse/CLOUD-3200.

Tested with Business Central (RHPAM) images and I was able to create a keycloak client configuration with URLs from the application routes where the pod is running.

The logic between this "discover" is to use the pod hostname. If a route is found with this name, we set the APPLICATION_ROUTES to it, then the script does the rest of the job and registers the keycloak client with the correct URLs.

Most of the time, templates create routes, services, pods, secrets with the same base name. So, if the template does not set the HOSTNAME_HTTP env variable, we try to found a URL based on this base name.

For this to work, I borrowed these functions from our code base (jboss-kie-modules):

• query_route
• query_route_host
• build_simple_url
• build_route_url

I tried to keep them agnostic to the use case, so we could easily export those to a common module in this repo. This would require the BA cloud team to add this new dependency to our images. That's why I'd like to discuss this matter with @errantepiphany and @spolti

So, before merging this one, I believe that we have to decide which path to go and/or if this feature make sense for you.

I made a couple comments regarding the "secure-" prefix, and open to opinions on it.

LGTM, thanks @ricardozanini

One final note, there aren't any tests, if you could write some bats tests just to verify the output of the functions, that would be really great.

Guys,

I reviewed the entire scenario, reduced the scope and made a real clean up. Now we don't rely from kie-modules anymore (just a small error handling). The only "problem" now is the python dependency. Tomorrow I'll write bats tests and do the integration tests. @luck3y please hold this one until I finish these tests.

@errantepiphany @luck3y please let me know your thoughts. ❤️

@ricardozanini , looks good to me, but will defer to @luck3y , as he is the gatekeeper of jboss-eap-modules.

Ignore the CI error, this was from a hung previous job.
