Move HttpContext property from OutputFormatterWriteContext to OutputFormatterCanWriteContext

[khellang]

I'm doing some resource versioning using an IOutputFormatter and would like to provide other mechanisms of versioning than just using the Accept header, like using a custom header, or even the URI for that matter.

This is not possible today (AFAIK) because theHttpContext property sits in OutputFormatterWriteContext rather than OutputFormatterCanWriteContext.

Would it be possible to move the property up a level? See dev...khellang:move-http-context-up for an idea of what I'm talking about.

This sounds reasonable to me. @Eilon @rynowak Any concerns?

[rynowak]

yeah seems fine, this just seems like an oversight on our part

Looks like #5316 was merged but we forgot to close this issue.
