storcon: use diesel-async again, now with tls support (#10614)

Successor of #10280 after it was reverted in #10592.

Re-introduce the usage of diesel-async again, but now also add TLS
support so that we connect to the storcon database using TLS. By
default, diesel-async doesn't support TLS, so add some code to make us
explicitly request TLS.
