The io/ioutil package has been deprecated in Go 1.16. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

Taking the same approach as was taken in containerd
The new library has a slightly different output;
- keys at the same level are sorted alphabetically
- empty sections not omitted (`proxy_plugins`, `stream_processors`, `timeouts`),
which could possibly be be addressed with an "omitempty" in containerd's struct.
- empty slices are not omitted (`imports`, `required_plugins`)
After sorting the "before" configuration the diff looks like this:
```patch
diff --git a/config-before-sorted.toml b/config-after.toml

In the containerd supervisor, instead of polling the healthcheck API
every 500 milliseconds we can just wait for the process to exit.

also renamed the non-windows variant of this file to be
consistent with other files in this package

`time.After` keeps a timer running until the specified duration is
completed. It also allocates a new timer on each call. This can wind up
leaving lots of uneccessary timers running in the background that are
not needed and consume resources.
Instead of `time.After`, use `time.NewTimer` so the timer can actually
be stopped.
In some of these cases it's not a big deal since the duraiton is really
short, but in others it is much worse.
