Snyder default info

[brenthosie]

Description

#91 was opened by @jonsnyder in 2023. Rather than having @jonsnyder resolve the conflicts, I've done that here on his behalf.

Motivation and Context

This adds a new api endpoint "/defaultInitInfo/:type/:name" which returns the default init info for a component. This api endpoint calls a user specified callback to modify the initInfo, getDefaultInitInfo. This is useful for generating and setting an access token or setting up custom defaults for extensionSettings or other properties in the initInfo.
