Add ability to disable auto-correct for a single linter

[gael-ian]

Currently this gem does not allow to disable auto-correct for a single linter in its configuration. This could be useful to check offenses in code but let developpers fix them by hand. Recently added linter for strict locals is a good example: its auto-correct add <%# locals: () %>\n at the beginning of a view partial but doing so break it as no locale variables will be allowed to be passed on a render call.

RuboCop allows to disable auto-correct per cops and it should be nice to be able to do the same thing in ERB lint.
