Add option to sanitise data

[dosaboy]

Some people might want to run this tool in production environments that contain sensitive data e.g. passwords, that they do not wish to share in the public domain. It would be nice to have an option (or perhaps just do this by default) to sanitise data pulled.

A tool that has served us for this purpose for many years (collect data and then sanitize it) has been sosreport ( https://github.com/sosreport/sos/ ), it contains code to remove passwords and other things that could be reused.
