Allow two DRM certificates for each identifier

Browse Source 
[ Merge of http://go/wvgerrit/119684 ]

This allows for a default DRM certificate that includes an expiration
time and a legacy one without for each app+origin specific identifier.
Existing offline licenses/secure stops are not associated with a
certificate, and so we cannot delete legacy certificates even after
fetching a new one. New offline licenses/secure stops will be associated
with certificate information, so we will not have this problem going
forward.
