Remove Dependency on SFA Trust #472
Description
Geni-ch has several remaining dependencies on the SFA trust code (in geni-tools). It would be better to remove this dependency on this unsupported body of code. Here are the dependencies:
DelegateBase credential
HandlerBase certificate
ArgumentCheck certificate
MAV1Implementation gid, certificate
PGCH xrn, gid
SAV1Implementation gid, certificate
cert_utils certificate
SpeaksFor certificate, credential, credential_factor, gid
