Summarization

When attempting to use a new Component from an out-of-scope namespace a completion item should be presented that will auto-insert the appropriate using statement at the top of the file to ensure that component is inserted in scope.

Current experience

Proposed experience

Since LSP in VS doesn't expose a way to specify additional text on an item, we should just have the display of the completion item be "Component - @using The.Namespace"

This completion item should be in addition to the existing fully qualified component name, so muscle memory isn't broken
