Subject: [PATCH] codership/galera#647 Generate keys and certificates for SSL
tests
Relying on static certificates causes several problems:
- Certificates eventually expire, which causes surprises
when tests suddenly stop passing without prior warning.
- Standards change, a certificate created on different
platform long time ago may not be usable on some more
modern platform.
- Lack of fine grained control on test scenarios without
generating and storing several certificates in source
repository.
In order to work around the problems above, generate
certificates programmatically before the tests are run.
The generated certificates use the same versioning and
extensions as the original ones under tests/conf.
