I recently bought a used ipad air 2 from ebay. But when i tried to do the initial setup i an taken to a configuration page that is essentially a mobile device management setup which essentially says the ipad is remotely configured by someone else. Then when i try to proceed with the configuration its asks for a username and password. which has not been given to me. do u guys know how i can remove this? 
I am perfectly fine with jailbreaking the etc.

This is the DEP enrollment screen. Contact the business that manages that device to either return it to them or have them release the device from management. Only they can release that hardware by Apple policy.
If you don't want to hassle with a potentially stolen iPad, contact eBay to see about a refund or how they handle sales of goods materially different than advertised. (on the assumption you didn't bid on a locked iPad)
