Added SNI support for os_sahara role via OS packages

Some Linux distributions, such as CentOS 7 and Xenial, have trouble
validating SSL certificates when using get_url with servers
that use Server Name Indication (SNI).

This patch adds those packages to the list of required packages and
uses bindep to install them in developer test environments the same
way that the gate tests install them.
