https://github.com/containerd/containerd/pull/8143 added an alias for
logrus.Fields and moved over most usages to this alias, but there was
one straggler.

We pass in a callback using the ttrpc.WithOnClose functionality
for shims that use ttrpc, but with the newly added ability to use
GRPC for shims this was left as a follow-up. It doesn't seem like
grpc-go has anything similar so some options (that I could see) are:
This change introduces a new grpcConn wrapper type for the connection
that exposes a method to get notified when the users callback has run,
the same in functionality as TTRPC's `UserOnCloseWait`. The callback
gets passed in in a new `grpcDialContext` function that will:
1. Dial the connection as normal
2. Spin off a goroutine that will monitor the connections state
until it transitions to idle or shutdown and will then run the
callback.

- When tracing code, it was a bit hard to understand what the third parameter is.
- The current comment should be enough to understand how to use LoggerFunc,
and people who want to learn more can click into the doc link.

This updates the runtime/v2 README to state the experimental GRPC support
for shims and how to choose the protocol.

Recent work added the ability to use grpc for shims, it'd be nice to
have a debug (or info perhaps) log to show what protocol and addr the
shim sent over.

- Add Target to mount.Mount.
- Add UnmountMounts to unmount a list of mounts in reverse order.
- Add UnmountRecursive to unmount deepest mount first for a given target, using
moby/sys/mountinfo.

In Go 1.16 `net.ErrClosed` was exported, removing the need to check the
exact text of "use of closed network connection". The stdlib's net listeners
are all setup for this to be a reality, but on Windows containerd uses the
the go-winio projects named pipe implementation as the listener for services.
Before version 0.6.0 this project returned a different error named
`ErrPipeListenerClosed` for using a closed pipe, where this error was just
an `errors.New` with the same text as `net.ErrClosed`, so checking against
`net.ErrClosed` wasn't possible.
Starting in 0.6.0 go-winio has that error assigned to `net.ErrClosed` directly
so this *should* be alright to finally change.
