Add feature to show details about Quickload Site in Data Source tab of Preference window

IGB switches between primary and secondary Quickload site, that can be understood from background color of Quickload site link (yellow for Secondary, red if there is some exception , grey when primary). But this does not give developers clear picture of other details which we maintain about all the quickload sites.

Thus, this task is about adding a feature to show details about Quickload Site in Data Source tab of Preference window.

Approach decided is:
1. Add a info column as right most column and show blue icon with 'i' as we have it in IGB platform.
2. On clicking on info icon it should show details related to Quickload site in small text accommodating pop-up window. This pop-up should have copy feature. cancel and close buttons.
