Add TLS data to call-home yang-models
The configuration model for callhome-server does not allow TLS to
be configured -- i.e. we are blindly assuming the devices will be
connecting via SSH.
Rectify this by deprecating the old configuration leaf and adding
the option to configure authentication on a per-transport basis.
