[Admin Tools] Layout of Account admins page updated to table

Problem statement:

the account admins page currently is just a long list of names with role and email address. it's hard to find people cross reference who has which role, in which sub account and keep track of permissions. it is a real headache to manage all the admin permissions with the current screen also bearing in mind you have to go to each sub account admins screen to view and amend. there is no visibility of a user and which sub account they have and which admin permissions they have in those sub accounts.

Proposed solution:

IT would be really great if this page were converted into a table (like the permission set) showing name on left with email address then columns for each role type and ticks against where roles added. with only one line per person so you could easily see if someone had been given more than one role and potentially easily just add ticks or remove ticks. (again like the permission sets screen). also would be good to show on user/admin profile which sub accounts they have admin access and with what role.

User role(s):

admin
