Feature Change - Enable a Custom HTTPS Certificate for use

The current implementation of OSDU on Azure utilizes an auto provisioned HTTPS certificate by using cert-manager.

As a user of OSDU I should be able to utilize a custom certificate of my choosing to handle https ingress on my deployment of OSDU.
