The default cache for a cachedTokenSource is not always empty. In the
case of commandTokenSource, it contains calling details for the
external command that is used to generate refresh tokens. Persisting
a completely empty cache will thus break ability for the plugin to
obtain refresh tokens. This changes the roundtripper to persist
the default cache instead of assuming an empty map.

Add the:
- mandatory flag "--config" to the preflight phase
and parse the specified config file for either "master" or "node".
- flag "--ignore-preflight-errors" to the preflight phase to
allow skipping errors.
- the function AddIgnorePreflightErrorsFlag()
to "options/generic.go", because the flag is used in multiple commands.
