MEDIUM: httpclient: initialize the httpclient with default SSL values

The current httpclient implementation does not initialize its server
with the options from the global section: ciphers, ciphersuites and
various SSL options are always the default of the SSL library.

This patch changes the behavior and apply the ssl-default-server-*
keywords to the httpclient SSL server.
