afb-context: Move credentials to context
The split between context and credentials in requests was somehow artificial and awkward. This change move the credentials to the context and removes as many references to credentials as possible in favor of working on contexts. Change the value returned by afb_auth_check to be 1 if validated, 0 or less than zero if not validated. Bug-AGL: SPEC-2968 Signed-off-by: José Bollo <jose.bollo@iot.bzh> Change-Id: I979dc841e03247e126e3fa8433a1cc0d4108adf0
