Rename parameter_overwite_by_rails_rule to parameter_overwrite_by_rails_rule

[r7kamura]

"overwite" is probably a typo for "overwrite" ?

• add parameter_overwite_by_rails_rule option #374

[ydah]

This option has already been released in v5.0.0, so it would be a good to change it while maintaining backwards compatibility.
It would be a good to proceed as follows in stages.

1. Add parameter_overwrite_by_rails_rule option to indicate to use it (or print a warning)
2. Release the above as a minor version update
3. Delete parameter_ overwrite _by_rails_rule during the next major version update

Excellent point @ydah! It'd be great to fix this, and we should, but given that it was released already, we should be a little more careful about it.

@r7kamura Thank you for change! Sorry about the long delay here, but if you make the requested update above, we'll try to get it ushered in.

[r7kamura]

OK, I've added one more commit to support the "overwite" one as well, so please check it out.

@r7kamura Thank you! Looks good!
I think this is a change that should be communicated to users, so could you add a description of the change in the CHANGELOG?

[ydah]

Thank you!
