Subject: [PATCH 1/9] gp: Support more global trust directories
In addition to the SUSE global trust directory, add support for RHEL and
Debian-based distributions (including Ubuntu).
To determine the correct directory to use, we iterate over the variants
and stop at the first which is a directory.
In case none is found, fallback to the first option which will produce a
warning as it did previously.

Subject: [PATCH 5/9] gp: Convert CA certificates to base64
I don't know whether this applies universally, but in our case the
contents of `es['cACertificate'][0]` are binary, so cleanly converting
to a string fails with the following:
'utf-8' codec can't decode byte 0x82 in position 1: invalid start byte
We found a fix to be encoding the certificate to base64 when
constructing the CA list.
Section 4.4.5.2 of MS-CAESO also suggests that the content of
`cACertificate` is binary (OCTET string).
