Create/Update project by importing Project.yaml file

[christad92]

As a user, I want to be able to create a new project or update (overwrite) my project by importing a project spec (project.yaml) file.
When attempting to create a new project, we should extend the Create new project dialog to allow users to choose if they want to import a project spec file or build from scratch.

To update an existing project, we should add a new action in the project setting that allows users to import a project by specifying the project.yaml file. This process overwrites the existing version of the project with the project spec in the imported file.
