Define the server setup builder and use it. While this adds some extra
code (overhead) now, it will enable more dynamic server configurations
later (e.g. conditional configuration).
Fix typo in function name.
Fix issue when setting up server certificates: use the correct array
object in the builder.
Fix issue during server setup: only tell the server to support all
secure SSL protocol versions when the test didn't specify any
versions.
Fix an when setting up the server: don't return from the 'config server' function
early, failing to set the enabled SSL protocols.
