- 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.

Both names have no real sense, but one allows to make sure these packages

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.
