Subject: Added support for https
X-Git-Tag: BronzeRC0~9
X-Git-Url: https://gerrit.o-ran-sc.org/r/gitweb?a=commitdiff_plain;h=0bcfde8903ba3f1fb99fcab3bf39f7f4e6ccbe1e;p=portal%2Fnonrtric-controlpanel.git

Added support for https

The backend listens to port 8434 for https.
Port 8080 is still open for http

In this commit, the backend uses http://policy-agent-container:8081 towards the
policy agent.
Using https://policy-agent-container:8433 is tested.
