currently updating the fingerprints using `pmgcm update-fingerprints`
runs into an error indicating that parsing of the remote node's
fingerprint fails
The error is due to changed output in openssl's x509 command,
introduced in commit:
91034b68b39e3525f09fb263b9272de410a3ba4c
in openssl upstream [0]
Note that in that case it would equally work to change the parameter
from `-sha256` to `-SHA256` in the `openssl x509` command above
The change seems small enough to warrant pulling it into stable-7 as
well (although the issue should not occur in systems upgraded
according to our howtos).

To: pmg-devel, Stoiko Ivanov
could be made more robust by wrapping "read_local_ssl_cert_fingerprint"
somewhere callable via SSH (so that we have a single way of doing file
path -> cert -> fingerprint) but this serves as a stop-gap measure.
I wonder whether we should lower-case the cache (key) in
PVE::APIClient::LWP, to reduce a potentially confusing source of errors?
some tools use aa:bb:.. , some other use AA:BB:.. for fingerprints, but
they are semantically equivalent..
folded in shortening the RE, now that it's case-insensitive anyway we
don't need to match both A-F and a-f ;)
