Add fields to describe vehicle locks

Is your feature request related to a problem? Please describe.

Cities often include policies on locks and locking vehicles so they want to be able to track if vehicles have a lock (or not) and when that lock is in use (or not) as part of the data their getting via MDS.

Describe the solution you'd like

Add a new field for lock that would be used in the same way as vehicle_type or propulsion_type. Not sure if this could be a yes/no field or if there are lock types that would be useful to capture.

Add a new field for lock_status that would be used in the same way as battery_pct. This could probably be expressed as a simple on/off or 0/1.

Is this a breaking change

• No, not breaking

Impacted Spec

For which spec is this feature being requested?

• agency
• provider

Describe alternatives you've considered

Currently there's no way to get this data.

Additional context

Review the agency and provider portions of the MDS specification, comparing the existing vehicle_type, propulsion_type, and battery_pct fields. Resolve whether lock and lock_status need defined types or values, then specify both fields without a breaking change; done means the requested vehicle-lock data is unambiguously represented in both impacted specs.
