Octavia uses PKI in order to securely communicate over REST between
the control plane and the amphorae. However, there is no option to
currently configure these options at the moment.
This patch adds a class which helps configure these options to be
able to successfully communicate with PKI. It is important that
the SSL certificates must still be generated by the user.
