refactor(header): change HttpDate to opaque over SystemTime

Browse Source 
This removes the need for someone to use the `time` crate to create a
date compatible with HTTP headers. It now works with the `SystemTime`
type from the standard library.

BREAKING CHANGE: `HttpDate` no longer has public fields. Convert between
  `HttpDate` and `SystemTime` as needed.
