REGTEST: ssl: test "set ssl cert" with separate key / crt

This reg-test tests the "set ssl cert" command the same way the
set_ssl_cert.vtc does, but with separate key/crt files and with the
ssl-load-extra-del-ext.

It introduces new key/.crt files that contains the same pair as the
existing .pem.

+#REGTEST_TYPE=devel

+# This reg-test uses the "set ssl cert" command to update a certificate over the CLI.
+# It requires socat to upload the certificate
+#
+# this check does 3 requests, the first one will use "www.test1.com" as SNI,
+# the second one with the same but that must fail and the third one will use
+# "localhost". Since vtest can't do SSL, we use haproxy as an SSL client with 2
+# chained listen section.
+#
+# If this test does not work anymore:
+# - Check that you have socat
