Show progress or loader while making document upload request

[maulikmi]

Whenever any document goes for verification or uploading there is no progress bar shown or can not see any indicator.

• Let's say I have done Gov. Prof uploading it falls to the same screen to start Gov. Prof uploading and not even showing anything that says it doing some background operation to upload my previous scans.
• There is no feedback from buttons to indicate it is clicked. any feedback while clicking on any(Bingin verification etc) buttons will also be appreciated.
