Procedure to integrate AppSentinels provided modules
----------------------------------------------------
- AppSentinels provides 2 modules nginx_ext_auth_module.so and nginx_ext_access_log_module.so
- These modules can perform enforcement and/or logging of API traffic onto AppSentinels edge controller
- Refer to sample_nginx.conf for statements to integrate into your existing nginx.conf
	- Load the modules
	- Insert AppSentinels directive 'ext_auth_log_server' to point to URL where onprem-controller is reachable. This should be done for each server block
	- Perform nginx reload, 'service nginx restart'
