Use url::Url or allow passing strings to Redirect

[JadedBlueEyes]

Description of the feature

It would be ideal if Poem did not use its own Uri and insead used the url crate for type-interoperability with other crates, like reqwest, etc.

Code example (if possible)

At the moment I have to do this:

    // Takes `poem::Uri`, results in URL being validated needlessly
    Ok(Redirect::temporary(poem::http::Uri::from_str(redirect.as_str())?))

I would prefer:

    // Takes `Url` type  
    Ok(Redirect::temporary(redirect))

    // Takes `String` type  
    Ok(Redirect::temporary(redirect.to_string()))

You are right, so now the type is changed from Uri to impl Display.
