Add manage GRID license page to nvidia-settings UI

First time if user does not find /etc/nvidia/gridd.conf file create one from
available template /etc/nvidia/gridd.conf.template on the system.

Only users with sufficient privileges can update server address and port number.

If enableUI = FALSE do not show this Manage License page.
In case of VGPU show
            - current license state label, server address textbox, port no.
              textbox and Apply button.
In case of NMOS show Option to choose between
             1.GRID virtual workstation 2. Tesla (Unlicensed)

The License Edition section shows if your system has a valid GRID vGPU license.
If no valid license is listed, enter the address of your local GRID License
Server in the License Server box.
The address can be a domain name or an IP address.  If you want to use a port
number other than the default 7070, then enter it in the Port Number box.
Click Apply to assign the settings.

UpdateConfigFile() - used to parse gridd.conf and update it.
       NV_CTRL_ATTR_NVML_GPU_VIRTUALIZATION_MODE - used to decide the
       featureType.
nvidia-settings will query current license status from gridd daemon using DBUS
apis.
update_manage_license_info() - queries the current license status.
