uri fragments dropped?

[ibigbug]

Hi it seems the fragments part of a URI is dropped https://github.com/hyperium/http/blob/b53194720352ef923d5fa662bc52592520e8b3ce/src/uri/tests.rs#L210

can we added to the Uri struct?

It can be useful for certain connectors to do different logic base on the fragments that the users don't really want to pass to the remote HTTP server

See the discussion in #127 for some insights into that issue.
