Add OutputElementHintAttribute to control inherited TagHelper IntelliSense.

[NTaylorMullen]

Right now if you create a TagHelper <foo> which translates into a <ul> you miss out on any ul specific HTML IntelliSense when writing <foo. It'd be nice to have an attribute that would cause the HTML editor to inherit specified tag IntelliSense. AKA

[OutputElementHint("ul")]
public class FooTagHelper : TagHelper
{
...
}

Which would result in <foo invoking global and ul based IntelliSense.

Nice idea, crappy name. I'd go with something like [OutputElementName("ul")] or similar. We don't want to include VS-specific names in our APIs. This is really just a "hint" to the IDE in case it cares.

😄 👍 - Updated issue.

@DamianEdwards I'm thinking of adding support for multiple OutputElementNames like so:

[OutputElementName("ul", "div", "p")]
public class FooTagHelper : TagHelper
{
...
}

Which would indicate "give me all of the IntelliSense for ul, div, and p tags combined". Thoughts?

@NTaylorMullen Please add a tooling issue to tracking the tooling side of this work.

And the name is OutputElementHintAttribute.
