Attaches an advertiser to a Brand. An agent that works on that advertiser can then find this brand context. Send the same call again for the same result: the pair is the key, so a second attach writes nothing and still answers `201`. AdCrunch reads the provider from the advertiser. It does not take the provider from you. A Brand takes several advertisers, and an advertiser takes several Brands.

`POST /context/brands/{slug}/advertisers`
