On redhat based distribution, checking that USER_NS is compiled in the
kernel is not sufficient, we also have to check that the feature as
been enabled.
With this commit, it is now done by checking the content of
`/sys/module/user_namespace/parameters/enable`.

Removed unnecessary RUN statements and combined some of the RUN statement into a single line.
The runtime performance is seen as follows:

Fixes: #20709
As discussed in the issue, we need refine the message to
help user more understood, what happened for non-exist image.

This fix tries to improve the time to run TestRunUnshareProc
in #19425.
In this fix goroutines are used to run test cases in parallel to
prevent the test from taking a long time to run.
As the majority of the execution time in the tests is from
multiple executions of 'docker run' and each of which takes
several seconds, parallel executions improve the test time.
Since each 'docker run' is independent, the purpose of the
test is not altered in this fix.

This PR fix the DockerSuite.TestBuildDockerignoringWildDirs test
in #19425.
Instead of having multiple RUN instructions in Dockerfile for every
single directory tested, this PR tries to collapse multiple RUN
instructions into one RUN instruction in Dockerfile.
When a docker image is built, each RUN instruction in Dockerfile
will generate one layer in history. It takes considerable amount of
time to build many layers if there are many RUN instructions within
the Dockerfile. Collapsing into one RUN instruction not only speeds
up the execution significantly, it also conforms to the general
guideline of the Dockerfile reference.
Since the test (DockerSuite.TestBuildDockerignoringWildDirs) is
really about testing the docker build with ignoring wild
directories, the purpose of the test is not altered with this PR
fix.

Allows users to submit options similar to the `mount` command when
creating a volume with the `local` volume driver.
For example:
```go
$ docker volume create -d local --opt type=nfs --opt device=myNfsServer:/data --opt o=noatime,nosuid
```

This PR fix the DockerHubPullSuite.TestPullNonExistingImage test
in #19425. The majority of the execution time in this test is
from multiple executions of 'docker pull', each of which takes
more than one second even though it tries to pull a non-existing
image.
Without changing the behavior of the 'docker pull' itself, this
fix tries to execute the 'docker pull' command in parallel in
order to speed up the execution of the overall test.
Since each 'docker pull' is independent, executions in parallel
should not alter the purpose of the test.
