This brings ssl context handling in line with the async client.
Importantly, openssl has a pretty signifigant performance regression
in creating ssl contexts v3.0+ that is mitigated by paying the context
creation tax once, instead of for every request.

Based on testing, this reduces the openssl v3 performance penalty
from ~200ms per connection to 9ms per connection.
