Align CDS Propulsion types to MDS 2.0 options

[schnuerle]

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

CDS 1.0 uses 4 propulsion types, while MDS 2.0 now uses 8 propulsion types.

Describe the solution you'd like

CDS has language where this is to be updated in 1.1 to the MDS options:

"For this CDS release the list will be developed independently here to accommodate CDS and MDS use cases, while still aligning to the MDS design principles. In the next major MDS 2.0 release and next CDS release, alignment between CDS and MDS propulsion types can occur."

Is this a breaking change

• No, not breaking

Impacted Spec

For which spec is this feature being requested?

• Events

Additional Context

We may also want to align CDS vehicle types to MDS vehicle types where there is overlap, each way.
