Remove HttpResponseBuilder::json2() (#1903)

Browse source 
It's not necessary to keep both json() and json2() around since the
former reduces the ownership of its parameter to a borrow only to pass
the reference to the latter. Users can instead borrow themselves when
passing an owned value: there doesn't need to be two separate functions.

This change also makes HttpResponseBuilder::json() take T: Deref so it
can accept both references and web extractors like web::Json.

* Renamed `IntoHeaderValue::{try_into => try_into_value}` to avoid ambiguity with std
`TryInto` trait. [#1894]

* Remove `HttpResponseBuilder::json2()` and make `HttpResponseBuilder::json()` take a value by
reference. [#1903]
### Removed
* `ResponseBuilder::set`; use `ResponseBuilder::insert_header`. [#1869]
