Proposed changes

Problem: As a user of NGF I want to have the ability to configure the log format of NGINX's access and error logs So that I can easily collect logs from NGINX in my logging platform.

Solution: Adding log_format and access_log fields to nginx-proxy CRD, also adding default values for them

Testing: TODO

Closes #1200
