Eric Wild ccefc98160 smdpp: add proper tls support, cert generation FOR TESTING 
If TLS is enabled (default) it will automagically generate missing pem files + dh params.

A faithful reproduction of the certs found in SGP.26_v1.5_Certificates_18_07_2024.zip available at
https://www.gsma.com/solutions-and-impact/technologies/esim/gsma_resources/sgp-26-test-certificate-definition-v1-5/
can be generated by running contrib/generate_certs.py. This allows adjusting the expiry dates, CA flag,
and other parameters FOR TESTING. Certs can be used by the smdpp by running
$ python -u osmo-smdpp.py -c generated
