Improve documentation to include warnings for excess logging in production

The documentation provides instructions to increase logging levels for example

 

https://backstage.forgerock.com/docs/ig/6.5/gateway-guide/index.html#chap-logging

https://backstage.forgerock.com/docs/ig/6.5/reference/index.html#CaptureDecorator

 

increases in logging levels can prove helpful for debugging, however leaving log levels high in production can cause performance issues as well as consuming resources i.e. disk space.

An example is that some customers still have this in production:

 
{
"name":"capture",
"type":"CaptureDecorator",
"config":

{ *"captureEntity":true,* *"captureContext":true* }

}
 
This request is to provide "production warnings" of the consequences of leaving certain flags enabled i.e. captureEntity=true.
