moved some code to the component

This simply moves some code from a command to a dedicated class to make it more reusable.

I wasn't able to run tests because composer failed to install dependencies. Let's see if travis can do better.
fixed CS
[HttpFoundation] removed the username and password from generated URL as generated by the Request class (closes #5555)

Quoted from the ticket it solves for future reference:

"I've been having issues with using htdigest auth (requirement for me to
work with) after upgrading to 2.1. Each time a resource is loaded, a
prompt is given for the HTTP Auth username and password, and Chrome does
not automatically respond to these 401 responses with the credentials it
already has. I've traced the issue to being caused by the HttpFoundation
Component, specifically Request.php.

The request class adds the PHP_AUTH_USER/PHP_AUTH_PW parameters to the
request URI (changes http://www.mysite.com requests to
http://user:pw@www.mysite.com) in getSchemeAndHttpHost(). This behaviour
is not specified in the HTTP RFC, and is incompatible with Chrome as of
Chrome 19, IE (as of IE 9) and has special behaviour in Firefox (prompts
the user to confirm they know they're logging into the site, which is an
ambiguous behaviour at best, but at least it's something if they're
going to support it for now).

This functionality was added about to HttpFoundation about a year ago,
but it really should be removed and standard protocol practices should
be followed. This practice makes it possible for cross-site tracking and
other malicious behaviours to be performed by hiding information in the
authorization headers, which explains why most browsers no longer
support or take exception with it.

The offending line is specifically this. Replacing it with return
$this->getScheme().'://'.$this->getHttpHost(); seems to solve the
problem."
