registering content-length different than the actual body should have 2 different behaviours

[gabrielfalcao]

The first behaviour is:

import HTTPretty
HTTPretty.register_uri(HTTPretty.GET, "http://github.com/gabrielfalcao",
                       body="this is supposed to be the response",
                       adding_headers={
                           'Server': 'Apache',
                           'Content-Length': '23456789',
                           'Content-Type': 'application/json',
                       })

The expected content-length is 23456789 but the actual expected body has len 35

The DEFAULT behaviour is to raise an exception that says:

HTTPretty got inconsistent parameters. The header content-length expects size `23456789` 
but the body you registered for that has length `35`
Fix that, or if you really want that, call register_uri with "fill_with" callback. See the documentation for more.

Then the person can set the kwarg fill_with=lambda filedescriptor: "foobar", for example.
Or even use builtin callbacks such as:

import HTTPretty
HTTPretty.register_uri(HTTPretty.GET, "http://github.com/gabrielfalcao",
                       body="this is supposed to be the response",
                       fill_with=HTTPretty.zeros,
                       adding_headers={
                           'Server': 'Apache',
                           'Content-Length': '23456789',
                           'Content-Type': 'application/json',
                       })

raising exception when the developer register a content-length bigger than actual body size. closed by a796971

Oops, I missed to implement the callback :)

[gabrielfalcao]

The callback doesn't make sense since the developer can actually specify the body and the content-length
