AIESW-21287 add new qos parameter sleep_to_limit_fps

[mkorhone]

Problem solved by the commit

Add new qos parameter sleep_to_limit_fps to profile.json that can be used to simulate a model running at a fixed frame rate

Bug / issue (if any) fixed, which PR introduced the bug, how it was discovered

N/A

How problem was solved, alternative solutions (if any) and why they were rejected

Alternative solution is to use the existing sleep parameter in the iteration node in executions. This sleep duration is fixed, but since the sleep amount varies based on what else is running, it seems less brittle to automatically compute the sleep duration.

Risks (if any) associated the changes in the commit

None unless this new parameter is used. Otherwise, we should consider this parameter experimental.

What has been tested and how, request additional testing if necessary

Ran full model tests both with and without this new parameter

Documentation impact (if any)

Potentially could document this new parameter
