Improve handling of long-running processes that require browser response to user

During activities that require minutes-long wait times for a browser-based response, please provide runtime options to push activities to the background or disable certain checks. Examples:

1. For large ETL jobs, ADMM scans through all reports to do various metadata type checks. Sometimes this takes so long that (I believe) we run into a timeout on (the load balancer?) which causes a 504 Gateway timeout. For this specific example, provide the user an option to turn off these checks or in SKP parameters.

• The same 504 Gateway timeout can be found through recompiling objects of a large database. See Support ticket GateWay 504 Timeout Error – Software Support

Sean Clauson should be able to provide more context/detail.
