`scrub_fields` to accept list of regex-es. Feature request.

[bytnar]

Rails.application.config.filter_parameters allows to provide collection of regex-es like

Rails.application.config.filter_parameters += [
    /email/,
    /name/,
]

would be good to have rollbar supporting regex list too so that scrubbing fields could be easily configure like this:

config.scrub_fields |= Rails.application.config.filter_parameters

Currently rollbar respects list of symbols.
