support running inside both headless Dynamo and UI mode

[radumg]

Situation right now

Extension has most of the functionality in the ViewExtension

What new feature do you suggest ?

• Split functionality between Extension & ViewExtension
• use DynamoModel wherever possible instead of DynamoViewModel
• support using both and selectively enabling endpoints based on available Dynamo features

How would this feature improve it ?

Allow some features of DynaServer to work in a headless, cross-platform version of Dynamo too.

Are you ready to help build this feature ?

• Yes
• No

tried abstracting away commands in a ServerExtension but running into thread safety issues. Needs further investigation.
