Add support for multiple URL params

[weierophinney]

Currently, only optional params are exposed when looking at a service.

Example:

It'd be awesome to add support for non-optional params

Example:

In Service.php, in the toArray() method, this is happening:

$routeWithReplacements = str_replace(['[', ']', '{/', '{:'], ['{', '}', '/{', '{'], $service->route);

Changing it to:

$routeWithReplacements = preg_replace('#\[?\/:(\w+)\]?#', '/{$1}', $service->route);

will give the results I'd like to see.

If this change is acceptable, I can go ahead and make a PR, otherwise, I'm open to hearing other ideas to add support for this.
