Operator Support for missing leading slash and present trailing slash in http-relative-path

[vmuzikar]

This is a follow-up from #16736.

The Operator needs to support:

• missing leading slash, e.g. auth
• present trailing slash, e.g. auth/
• the combination of both, e.g. /auth/

Currently, the Operator expects the http-relative-path to have only leading slash (/auth).

Another thing to consider, is that if you use custom image with the operator, it will automatically add --optimized to start, which means that the build options configured by the operator won't have any effect. This was the problem in my case. I had to add the relative-path to the custom image. So maybe either make the --optimized configurable in the operator, or log some messages regarding the build option during startup.
