Description of changes:
This change adds more alert mappings, this time for certificate issues. This can provide a lot better insight into why the handshake is failing.
Call-outs:
One thing to note, as is still the case from #3171, this does not return alerts on the wire. It's only for the local TLS stack.
Testing:
I added
EXPECT_FAILURE_WITH_ALERT
in a couple of places to show the mappings coming through.Long term, it would be nice to have some kind of snapshot tests for these mappings so we can be more exhaustive on the checks.
