Add support for hashing time.Time within slices, which unbreaks auditing of requests returning the request counters.  

Break Hash into struct-specific func like HashAuth, HashRequest. Move all the copying/hashing logic from FormatRequest/FormatResponse into the new Hash* funcs.  HashStructure now modifies in place instead of copying.

Instead of returning an error when trying to hash map keys of type time.Time, ignore them, i.e. pass them through unhashed.

Enable auditing on test clusters by default if the caller didn't specify any audit backends.  If they do, they're responsible for setting it up.

Earlier in tokenutil's dev it seemed like there was no reason to allow
auth plugins to toggle renewability off. However, it turns out Centrify
makes use of this for sensible reasons. As a result, move the forcing-on
of renewability into tokenutil, but then allow overriding after
PopulateTokenAuth is called.

This drastically reduces boilerplate for upgrading existing values

* Update github to tokenutil

* Update phrasing

This was inspired by #7022 but has the advantage of avoiding
double-locking and needing to perform lock upgrades while also
simplifying the logic and being faster.
