The following failure is seen in CI from time to time:
> FAIL: docker_api_containers_test.go:435: DockerSuite.TestContainerAPITop
>
> docker_api_containers_test.go:453:
> c.Assert(top.Processes[0][10], checker.Equals, "/bin/sh -c top")
> ... obtained string = "top"
> ... expected string = "/bin/sh -c top"
The test case expects two processes in the output:
1. /bin/sh -c top
2. top
in the given order.
Now, "ps aux" output is sorted by PID*, and so since the "top" is a child
of "/bin/sh -c top" it has a higher PID and will come second as expected
by the test... unless the PIDs on the system are exhausted and PID rollover
happens, in which case PID of "top" will be lower than that of "/bin/sh".
Fix: sort output by process name.
* - in fact it is not sorted, but is being printed in the same order as
the kernel list PID entries in /proc directory, which appears to be
sorted by PID (see ls -1 -U /proc).

`arm64` needs get more time duration for the test to finish.
`pty.Start()` opens a file, so the caller should close it explicitly,
else the file I/O can result in unexpected data synchronization issue.
All those changes will not affect the test itself.

This issue has been reported by issue #36877.
The purpose of this test case is for the regression test of #12546,
so we only need to make sure the essential of the testing is still
in the way to check that while not disturbed by some testing noises,
which is exactly what this PR want to do.

Let's use strings for comparisons to make the output more readable.
While at it,
- get the container's stderr as well, and make sure it's empty;
- check that stdcopy.StdCopy() did not return an error, except for
the timeout which is expected;
- move/remove comments, simplify var names.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

Functions `GetMounts()` and `parseMountTable()` return all the entries
as read and parsed from /proc/self/mountinfo. In many cases the caller
is only interested only one or a few entries, not all of them.
One good example is `Mounted()` function, which looks for a specific
entry only. Another example is `RecursiveUnmount()` which is only
interested in mount under a specific path.
This commit adds `filter` argument to `GetMounts()` to implement
two things:
1. filter out entries a caller is not interested in
2. stop processing if a caller is found what it wanted
`nil` can be passed to get a backward-compatible behavior, i.e. return
all the entries.
A few filters are implemented:
- `PrefixFilter`: filters out all entries not under `prefix`
- `SingleEntryFilter`: looks for a specific entry
Finally, `Mounted()` is modified to use `SingleEntryFilter()`, and
`RecursiveUnmount()` is using `PrefixFilter()`.
Unit tests are added to check filters are working.
[v2: ditch NoFilter, use nil]
[v3: ditch GetMountsFiltered()]
[v4: add unit test for filters]
[v5: switch to gotestyourself]

All `plugins` tests that require an `ExperimentalDaemon` are migrated
to `integration/plugin/*` and start an experimental daemon to test on
it.
The end goal being to remove the `experimental` build.
