This change sets an explicit mount propagation for the daemon root.
This is useful for people who need to bind mount the docker daemon root
into a container.
Since bind mounting the daemon root should only ever happen with at
least `rlsave` propagation (to prevent the container from holding
references to mounts making it impossible for the daemon to clean up its
resources), we should make sure the user is actually able to this.
Most modern systems have shared root (`/`) propagation by default
already, however there are some cases where this may not be so
(e.g. potentially docker-in-docker scenarios, but also other cases).
So this just gives the daemon a little more control here and provides
a more uniform experience across different systems.

This fix tries to address the issue raised in 36083 where
`network inspect` does not show Created time if the network is
created in swarm scope.
The issue was that Created was not converted from swarm api.
This fix addresses the issue.
An unit test has been added.
This fix fixes 36083.

Fixes#19803
Updated the json-logger to utilize the common log option
'tag' that can define container/image information to include
as part of logging.
When the 'tag' log option is not included, there is no change
to the log content via the json-logger. When the 'tag' log option
is included, the tag will be parsed as a template and the result
will be stored within each log entry as the attribute 'tag'.
Update: Removing test added to integration_cli as those have been deprecated.
Update: Using proper test calls (require and assert) in jsonfilelog_test.go based on review.
Update: Added new unit test configs for logs with tag. Updated unit test error checking.
Update: Cleanup check in jsonlogbytes_test.go to match pending changes in PR #34946.
Update: Merging to correct conflicts from PR #34946.

The idea behind making the graphdrivers private is to prevent leaking
mounts into other namespaces.
Unfortunately this is not really what happens.
There is one case where this does work, and that is when the namespace
was created before the daemon's namespace.
However with systemd each system servie winds up with it's own mount
namespace. This causes a race betwen daemon startup and other system
services as to if the mount is actually private.
This also means there is a negative impact when other system services
are started while the daemon is running.
Basically there are too many things that the daemon does not have
control over (nor should it) to be able to protect against these kinds
of leakages. One thing is certain, setting the graphdriver roots to
private disconnects the mount ns heirarchy preventing propagation of
unmounts... new mounts are of course not propagated either, but the
behavior is racey (or just bad in the case of restarting services)... so
it's better to just be able to keep mount propagation in tact.
It also does not protect situations like `-v
/var/lib/docker:/var/lib/docker` where all mounts are recursively bound
into the container anyway.

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.

It's a common scenario for admins and/or monitoring applications to
mount in the daemon root dir into a container. When doing so all mounts
get coppied into the container, often with private references.
This can prevent removal of a container due to the various mounts that
must be configured before a container is started (for example, for
shared /dev/shm, or secrets) being leaked into another namespace,
usually with private references.
This is particularly problematic on older kernels (e.g. RHEL < 7.4)
where a mount may be active in another namespace and attempting to
remove a mountpoint which is active in another namespace fails.
This change moves all container resource mounts into a common directory
so that the directory can be made unbindable.
What this does is prevents sub-mounts of this new directory from leaking
into other namespaces when mounted with `rbind`... which is how all
binds are handled for containers.

Instead of having to create a bunch of custom error types that are doing
nothing but wrapping another error in sub-packages, use a common helper
to create errors of the requested type.
e.g. instead of re-implementing this over and over:
```go
type notFoundError struct {
cause error
}
func(e notFoundError) Error() string {
return e.cause.Error()
}
func(e notFoundError) NotFound() {}
func(e notFoundError) Cause() error {
return e.cause
}
```
Packages can instead just do:
```
errdefs.NotFound(err)
```
