REGTEST: ssl: improve the "set ssl cert" test

Improve the test by removing the curl command and using the same proxy
chaining technique as in commit 3ed722f ("REGTEST: ssl: remove curl from
the "add ssl crt-list" test").

A 3rd request was added which must fail, to ensure that the SNI was
effectively removed from HAProxy.

This patch also adds timeouts in the default section, logs on stderr and
fix some indentation issues.

 # This reg-test uses the "set ssl cert" command to update a certificate over the CLI.
-# It requires socat and curl to upload and validate that the certificate was well updated
-
+# 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 and curl
-# - Check that the curl -v option still return the SSL CN
+# - Check that you have socat
