Support for named arguments in service definitions

[stof]

For autowired services, Symfony 3.3+ supports using named arguments when one of the argument must be wired manually, instead of positional arguments:

services:
    foo:
        class: Baz
        arguments:
            '$formatter': '@my_formatter'

<service id="foo" class="Baz">
    <argument key="$formatter" type="service" id="my_formatter" />
</service>

Currently, the bundle validates this against the type of the first argument, which is the wrong check.

note that named arguments are triggered for keys starting with a $. String keys not starting with a $ have no special meaning (and are deprecated)

The completion for $arg keys is not working for me in YAML services config.

Is that implemented yet?
