Merge pull request #689 from nginx/map-variables-flags

This commit changes the list of NGINX Agent variables to a table showing 
how it maps to the CLI flags, with an exception for the variable that 
doesn't have a flag yet.  It links to the CLI flag section so that the reader
can view the descriptions for additional context.

 To connect your NGINX Agent container to your NGINX One or NGINX Instance Manager instance, you must enable the gRPC interface. To do this, you must edit the NGINX Agent configuration file, *nginx-agent.conf*. For example:
 
 ```yaml
-erver:
+server:
   host: 127.0.0.1 # mock control plane host
   grpcPort: 54789 # mock control plane gRPC port
