API verification controller implementation

[Agupane]

Description

• Together with the ´KlerosController´ we may support an ´APIController´ (or similar, name TBD) that allows to verify badges that are supported by centralized entities that allow OAuth authentication (emails, social accounts, etc). In that what we could ask the creator to setup the oauth url's and we can manage that as a evidence and automatic prompt the user to verify against the provider.

It may be interesting that these models pass though a curation process before being available to use, and the ones that are verified by us should have a distintictive display among others, because this method may be used to generate fake oauth providers to stealth users information, so a review from our team may be needed.

More details TBD
