Missing ability to provide scope ID to config fixture service

[Vinai]

The config fixture step provides the ability to specify a config scope (that is "default", "website" or "store"). For example:

When I set config value for "some/config/path" to "1" in "store" scope

The problem is, to be usable with anything but "default", a scope identifier needs to be specified, for example as follows:

When I set config value for "some/config/path" to "1" in "store" "usa" scope

In the table core_config_data the scope ID is stored as an integer ID, using 0 for the "default" scope.
To make this more reusable the scope ID should be specifiable as a website or store view code.
