Prevent Parameter Typos

Was it ignoreFiles? Or ignored_files? Or ignore_file? Are you lazy to read every README.md to find out the correct name? Make developers' live happy by helping them.

# app/config/services.yaml
parameters:
    correctKey: 'value'

    # you need to get just this one right :D
    correct_to_typos:
        # correct key name
        correct_key:
            # the most common typos that people make
            - 'correctKey'

            # regexp also works!
            - '#correctKey(s)?#i'

This way user is informed on every typo he or she makes via exception:

Parameter "parameters > correctKey" does not exist.
Use "parameters > correct_key" instead.

They can focus less on remembering all the keys and more on programming.
