Ability to show customer detail fields in the Customers page

Summary:

At this moment, the Customers page of a service project only shows the following fields:
Name, Open requests, Closed requests, Status and Actions

You need to click on a customer's name to check the values added in the customer details fields. It would be great if the project admin has permission to show/hide the detail fields as per the need.

Why is it required?:

A lot of manual work will be reduced for an admin if they need to get some information from a customer detail field for all the customers, provided that we are still waiting for the ability to export these details.
