No parameter filtering is implemented

[tombruijn]

The JavaScript package offers a Span.setParams function but no filterParameters option is implemented like in the other integrations.

We don't call setParams anywhere ourselves in the integration packages, so any params transmitted are user submitted.

• Is the lack of parameter filtering intentional?
• Do we require users to filter the parameters themselves before sending an error?

To do

If we are implementing something for this.

• Update parameter filtering guide: https://docs.appsignal.com/guides/filter-data/filter-parameters.html
• Update parameter filtering topic: https://docs.appsignal.com/application/parameter-filtering.html
• Add config option to JavaScript options page: https://docs.appsignal.com/front-end/configuration/
