Add a Cache decorator for any kind of dictionary

[AntoineLelaisant]

What about creating a configuration parameter that would allows to wrap the dictionary inside a Cache decorator ?

The config would looks like:

dictionaries:
    my_dictionary:
        type: key_value
        content:
            - foo: 'BAR'
            - bar: 'BAZ'
        cache: true

By default this parameter would be set to true, but when activated, it put the compiled content of the dictionary in the application cache.

This is probably pointless with the example above but could make sense with combine or callable dictionaries.
