add response.redirect() helper

[nggit]

Redirection is basically just to set the header and return an empty body:

@app.route('/example')
async def redirect_handler(response, **server):
    response.set_status(301, 'Moved Permanently')
    response.set_header('Location', 'http://example.com/')
    return ''

Now we can use a helper:

@app.route('/redirect')
async def redirect_helper_handler(response, **server):
    raise response.redirect('http://example.com/', code=301)

It's an instance of tremolo.exceptions.HTTPRedirect.

Note

• It's the only exception that is not considered an error. So it cannot be hooked with @app.error(301)
• Just like other exceptions, previous headers are also cleared, meaning you cannot Set-Cookie. Unlike the return '' way
