[Rails] Filter parameters not applied in logs

[jonian]

Parameter filtering not applied in Rails applications. Using the code below fixes the issue:

def log_inspect
  info = mirror.log_informations
  info[:effective_url] = filter_url_params(info[:effective_url])

  "EASY #{info.map{|k, v| "#{k}=#{v}"}.flatten.join(' ')}"
end

def filter_url_params(url)
  return url unless Loggable.rails_logger

  filters = Rails.application.config.filter_parameters
  filters = ActionDispatch::Http::ParameterFilter.new(filters)

  uri = URI.parse(url)
  uri.query = filters.filter(CGI.parse(uri.query)).to_query

  CGI.unescape(uri.to_s)
end

Should I submit a PR?

That would be great. Does it have to be tied to Rails though? Could we instead have some logic that one can register as a config any filtered params (for simplicity purposes they can only be a string or symbol to begin with) and have the logic to remove them here without the Rails dependency?

Thoughts?
