- Kept the same behavior as we previously had with Razor directive completions.
- Attempted adding additional functionalities such as lighting up Razor directive completion when completion was invoked on top of Razor directives (non-C#) but ran into issues involving the core HTML editor not consuming the new completion APIs yet. That's something we'll have to re-visit once they move to the new completion APIs.
- Added tests to validate all aspects of new completion APIs.
- Made completion provider turn on and off based off of feature flag.
