Allow partial strings on Rails filter_parameters for meta_data_filters

The Recent Rails template will generate `filter_parameters` with
*partial* strings, such as `:passw` and `:_key`. I think this library
should also allow such keywords to filter out, following the Rails
template.

https://github.com/rails/rails/blob/f838a7421228204bbc1e012ff9a3801ed598da80/railties/lib/rails/generators/rails/app/templates/config/initializers/filter_parameter_logging.rb.tt#L6-L8

This patch might be a breaking change because it will filter more
parameters than before, but to exclude them would be better than sending
probably sensitive parameters as they are.
