This PR contains a fix for moby/moby#30321. There was a moby/moby#31142
PR intending to fix the issue by adding a delay between disabling the
service in the cluster and the shutdown of the tasks. However
disabling the service was not deleting the service info in the cluster.
Added a fix to delete service info from cluster and verified using siege
to ensure there is zero downtime on rolling update of a service.In order
to support it and ensure consitency of enabling and disable service knob
from the daemon, we need to ensure we disable service when we release
the network from the container. This helps in making the enable and
disable service less racy. The corresponding part of libnetwork fix is
part of docker/libnetwork#1824

A linter (vet) found the following bug in the code:
> daemon/metrics.go:124::error: range variable p captured by func literal (vet)
Here a variable p is used in an async fashion by goroutine, and most
probably by the time of use it is set to the last element of a range.
For example, the following code
```go
for _, c := range []string{"here ", "we ", "go"} {
go func() {
fmt.Print(c)
}()
}
```
will print `gogogo` rather than `here we go` as one would expect.

1. Add = between the option and the argument, otherwise the argument
appears to be passed on to the linters directly, as in:
> DEBUG: [golint.8]: executing /home/kir/go/bin/golint
> -min_confidence 0.800000 ./10m ./api ./api/errdefs <...>
2. Fix setting the default for GOMETALINTER_OPTS -- the default
was -deadline (rather than --deadline).

The Golang built-in gzip library is serialized, and fairly slow
at decompressing. It also only decompresses on demand, versus
pipelining decompression.
This change switches to using the pigz external command
for gzip decompression, as opposed to using the built-in
golang one. This code is not vendored, but will be used
if it autodetected as part of the OS.
This also switches to using context, versus a manually
managed channel to manage cancellations, and synchronization.
There is a little bit of weirdness around manually having
to cancel in the error cases.

PR #36011 fixed almost all of the golint issues though
there is still one golint error:
https://goreportcard.com/report/github.com/docker/docker#golint
```
Golint is a linter for Go source code.
docker/daemon/reload.go
Line 64: warning: redundant if ...; err != nil check, just return error instead. (golint)
```
This fix fixes the last one.

Both lcow_parser.go and linux_parser.go are duplicating the error:
"invalid specification: destination can't be '/'"
This commit creates a new error called "ErrVolumeTargetIsRoot"
that is used by both linux_parser and lcow_parser and remove
the duplication in the code.
