* Fix issue with bare host or IP as endpoint
* Fix issue with localhost registries not defaulting to http.
* Move the registry template prep to a separate function,
and adds tests of that function so that we can ensure we're
generating the correct content.

Render cri registry mirrors.x.endpoints and configs.x.tls into config_path; keep
using mirrors.x.rewrites and configs.x.auth those do not yet have an
equivalent in the new format.
The new config file format allows disabling containerd's fallback to the
default endpoint when using mirror endpoints; a new CLI flag is added to
control that behavior.
This also re-shares some code that was unnecessarily split into parallel
implementations for linux/windows versions. There is probably more work
to be done on this front but it's a good start.
