Generated dicts also have keys and values for rules to apply

[alexey-pelykh]

The general idea:

If

responseDict = {'childDict': {'spam': 'eggs'}}

is formatted as

responseDict = {
    'childDict': {
        'spam': 'eggs'
    }
}

so should

generatedDict = {x: x for x in 'value'}

be formatted as

generatedDict = {
    x: x for x in 'value'
}

assuming force_multiline_dict is enabled. Also allows to achieve the following format if split_before_dict_set_generator is enabled:

generatedDict = {
    x: x
    for x in 'value'
}
