[Metadata] Validate Project Templates during editing

[maxceem]

Follow up from https://github.com/appirio-tech/connect-app/issues/2842

Currently, we have project templates JSON which have been evolved for some time.

• We have some old properties which we don't use anymore.
• We have some new properties which partially duplicate old properties but have some additional features.
• It's not easy to remember which properties we have.

We've created JSON schemas for Project Template JSONs https://github.com/appirio-tech/connect-app/issues/2842.

TODO

1. We can implement validation of the Project Template JSONs during editing.
2. If possible implement suggestions (autocomplete) based on the schema during editing.

@maxceem @RishiRajSahu - is this something we can accomplish before 1/15?

[maxceem]

I think no @acshields. This task still requires some research for implementation. Anyway, this is only to improve Metadata editing experience for admins, it doesn't block any functionality.

Thanks for the feedback @maxceem - I will remove from our January backlog and we can look at this at a later point.
