test/parseconf: Add support for required log messages on success
We want to test that the "obsolete" log message includes the name of the option. But test_parseconf.sh doesn't check for log content on success.
Similarly, our lzma, zstd, and nss tests should also test for logs from a successful launch. At the moment, they force a failure, then check the logs.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
