AC1) enable-sslkeylog is present as a build option when we are building OpenSSL. [one-off manual verification] AC2) When SSLKEYLOGFILE environment variable is used, a file with the TLS connection secrets is created. [automated testing, /CoreOS/openssl/Regression/RHEL-90853-Enable-sslkeylogfile-support]

.OpenSSL supports `sslkeylogfile` OpenSSL supports the `sslkeylogfile` format for TLS. As a result, you can log all secrets produced by SSL connections by setting the `SSLKEYLOGFILE` environment variable. [IMPORTANT] Enabling the `SSLKEYLOGFILE` variable poses an explicit security risk. Recording the exchanged keys during an SSL session allows anyone with read access to the file to decrypt application traffic sent over that session. Use this feature only in test and debug environments.
