Create a new container for each subtest, so that individual
subtests are self-contained, and there's no need to execute
them in the exact order, or resetting the container in between.
This makes the test slower (6.54s vs 3.43s), but reduced the
difference by using `network=host`, which made a substantial
difference (without `network=host`, the test took more than
twice as long: 13.96s).

- Don't set `PidsLimit` when creating a container and
no limit was set (or the limit was set to "unlimited")
- Don't set `PidsLimit` if the host does not have pids-limit
support (previously "unlimited" was set).
- Do not generate a warning if the host does not have pids-limit
support, but pids-limit was set to unlimited (having no
limit set, or the limit set to "unlimited" is equivalent,
so no warning is nescessary in that case).
- When updating a container, convert `0`, and `-1` to
"unlimited" (`0`).

Older API clients did not use a pointer for `PidsLimit`, so
API requests would always send `0`, resulting in any previous
value to be reset after an update:
Before this patch:
(using a 17.06 Docker CLI):
```bash
docker run -dit --name test --pids-limit=16 busybox
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
16
docker container update --memory=100M --memory-swap=200M test
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
0
docker container exec test cat /sys/fs/cgroup/pids/pids.max
max
```
With this patch applied:
(using a 17.06 Docker CLI):
```bash
docker run -dit --name test --pids-limit=16 busybox
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
16
docker container update --memory=100M --memory-swap=200M test
docker container inspect --format '{{json .HostConfig.PidsLimit}}' test
16
docker container exec test cat /sys/fs/cgroup/pids/pids.max
16
```

A client is already created in testenv.New(), so we can just
as well use that one, instead of creating a new client.

`testEnv` is a package-level variable, so protecting / restoring
`testEnv` in parallel will result in "concurrent map write" errors.
This patch removes `t.Parallel()` from tests that use this
functionality (through `defer setupTest(t)()`).
Note that _subtests_ can still be run in parallel, as the defer
will be called after all subtests have completed.

This fix moves helper functions containerIsStopped and
containerIsInState to integration/internal/container,
so that they could be used outside of integration/container.

1. Use integration/internal/exec, removing the getContainerSysFSValue().
2. Avoid repeating magic numbers, use a variable for those.
3. Fix order of arguments to assert.Equal (first "expected", then "actual").

An implementation of exec in TestUpdateCPUQUota had a few issues,
including resource leaking and calling both ContainerExecAttach and
ContainerExecRun. The last one makes the test flaky:
update_linux_test.go:136: expected cgroup value 20000, got: Error: Exec
command f923baf709525f6b38f6511126addc5d9bb88fb477eeca1c22440551090fa2bb
is already running
Fix by using the integration/internal/exec package.
While at it, use require/assert to further improve code readability.

Fixes an issue where if cpu quota/period is sent via the update API, the
values are updated in the stored container data but not actually sent to
the running container.
