Add settings in Control Hub to be able to

Add settings in Control Hub to be able to change the default number of partipipants per page in the troubleshooting segment for meetings.

As of right now, the default display for participants per page in the troubleshooting segment in CH is 25 (Used to be 50).
Despite the fact it can be manually changed every time to 50 or 100, it will save users a good amount of time to have the ability to change the default setting, especially if their meetings have a larger number of participants.
