Add HTTPS support in CTA CI

EOS5 does not handle HTTP protocol: only HTTPS.

Therefore the current HTTP CI support #216 (closed) only allows to test EOS4, but not EOS5.

See EOS-5679 for detailled issue and reason.

Clean up a bit configmaps for HTTP

The goal is to have only useful ones left in the orchestration folder:

• eos-config-quarkdb-http.yaml: EOS4 with HTTP only
• eos-config-quarkdb-https.yaml: EOS4 with HTTPS
• eos5-config-quarkdb-https.yaml: EOS5 with HTTPS

eos5-config-quarkdb-http.yaml makes no sense as xrood5 dropped HTTP support...
