Keycloak Variables are required when Keycloak is disabled

[dhaselhan]

Describe the bug

The Keycloak Server URL and Keycloak Realm are required to be set to open the documentation page, even when keycloak is not enabled.

To Reproduce

Do not set any Keycloak variables on the docker image
Run the image
Navigate to http://localhost:3000/api/v1/docs

You will receive the following error and a 500:
{"component":"app","level":"error","message":"Configuration property "keycloak.realm" is not defined","stack":"Error: Configuration property "keycloak.realm" is not defined\n at Config.get (/opt/app-root/src/app/node_modules/config/lib/config.js:182:11)\n at getSpec (/opt/app-root/src/app/src/routes/v1/docs.js:12:114)\n at /opt/app-root/src/app/src/routes/v1/docs.js:24:59\n at Layer.handle [as handle_request] (/opt/app-root/src/app/node_modules/express/lib/router/layer.js:95:5)\n at next (/opt/app-root/src/app/node_modules/express/lib/router/route.js:144:13)\n at Route.dispatch (/opt/app-root/src/app/node_modules/express/lib/router/route.js:114:3)\n at Layer.handle [as handle_request] (/opt/app-root/src/app/node_modules/express/lib/router/layer.js:95:5)\n at /opt/app-root/src/app/node_modules/express/lib/router/index.js:284:15\n at Function.process_params (/opt/app-root/src/app/node_modules/express/lib/router/index.js:346:12)\n at next (/opt/app-root/src/app/node_modules/express/lib/router/index.js:280:10)","timestamp":"2022-09-01T18:10:39.153Z"}

Expected behavior

When keycloak is not enabled, the app should not require Keycloak variables to be set
