When running a support bundle, we want to know how long each operation
(collect, redact, analyze) takes. This commit adds a new trace exporter
that records the start and end times of each operation, and then prints
a summary of the execution. The summary is also stored in the support
bundle.

Have all in-cluster analysers implement the same interface. This
will help with the implementation of code that requires making
calls to all analysers

* feat(redactors): Run redactors on an existing support bundle
Add redact subcommand to support-bundle to allow running redactors on an
existing bundle to creating a new redacted bundle.
The command will be launched like so
support-bundle redact <redactor urls> --bundle support-bundle.tar.gz
Fixes: #705
