Describe the bug

When implementing there appears the attribute "autocomplete" with the value "off" in the generated html. The w3c validator (https://validator.w3.org) throws the error that the attribute autocomplete is not allowed with the input type="checkbox".

Libraries:

• BootstrapVue: 2.0.3
• Vue: 2.6.10

Additional context

I'm not sure if it is a bug or if I miss something to avoid the autocomplete attribute in the input type="checkbox" tag.
