XX-10711 - configure Polycoms running 4.0+ to be able to use TLS.
Add the configuration options to Polycom config files in order to enable use of TLS.
Please note that configuration options are not available on sipXconfig UI.
Admins will have to set registration server transport to TLS and if it is the case outbound proxy transport to TLS. Port should stay to 0.

This issue also fixes some uinit tests and adds a lot more.
