Implement Shared Line Appearances (SLA)

Shared Line Appearances (SLA) is hardcoded to 0 in the various device template config files. It would be nice to have a SLA dropdown option in Provisioning → Templates → DSS Keys to use instead of “Line” type and the backend to support it properly.

You can always edit the templates to customize the parameters.

Right, well I would hate to need to manually unroll the whole loop in the script just to support SLA when it should be part of the UI
