certificate and verifying with curl and strict-sni that it works.

+# This reg-test uses the "add ssl crt-list" command to add a certificate over the CLI.
+# It requires socat and curl to upload and validate that the certificate was well updated
+
+# If this test does not work anymore:
+# - Check that you have socat and curl
+# - Check if haproxy and curl use the same ciphers
