[TwigHooks] Replace ParameterBag with the DataBag

[jakubtobiasz]

Currently, we've been using the ParameterBag from the Symfony's DI, but it's limit the types we can pass to it. So, I've created a custom DataBag providing a pretty neat DX.

Examples:

$dataBag = new DataBag(['some' => 'values]); # creating a data bag from array
$dataBag->has('key'); # checking whether it has a given key
$dataBag->key; # accessing a given key, so in the expression language we can write it as dataBag.key
