Mahmood Ali 5a487ac884 tests: prevent indefinite blocking in some tests
Noticed few places where tests seem to block indefinitely and panic
after the test run reaches the test package timeout.

I intend to follow up with the proper fix later, but timing out is much
better than indefinitely blocking.

Mahmood Ali 8453ce7d56 tests: setup libcontainer rootfs
Using statically linked busybox binary to setup a basic rootfs for
testing, by symlinking it to provide the basic commands used in tests.

I considered using a proper rootfs tarball, but the overhead of managing
tarfile and expanding it seems significant enough that I went with this
implementation.

Alex Dadgar 1e3c3cb287 Deprecate IOPS
IOPS have been modelled as a resource since Nomad 0.1 but has never
actually been detected and there is no plan in the short term to add
detection. This is because IOPS is a bit simplistic of a unit to define
the performance requirements from the underlying storage system. In its
current state it adds unnecessary confusion and can be removed without
impacting any users. This PR leaves IOPS defined at the jobspec parsing
level and in the api/ resources since these are the two public uses of
the field. These should be considered deprecated and only exist to allow
users to stop using them during the Nomad 0.9.x release. In the future,
there should be no expectation that the field will exist.

Mahmood Ali 428d35a5a9 executor: Keep 0.8.6 exit code for wait() failures
0.8.6 uses exit code 1 when `proc.Wait()` fails: https://github.com/hashicorp/nomad/blob/v0.8.6/client/driver/executor/executor.go#L442

no t.Parallel() in excutor table driven tests (#4948)
When `t.Parallel()` is used inside a `t.Run()` sub-set, the closure
doesn't behave as expected, and some cases effectively get skipped.
More details can be found in

Mahmood Ali 2516cb16b9 Kill all container processes on shutdown
Currently, libcontainer-based executor, upon shutdown, kills the
container initial process.  The children of the killed process remain
running, and the executor is never marked as terminated until they do.

Also, fix a case where we treat processes as successful, when
`proc.Wait()` fails.  In some attempts, I was getting "waitid no child
processes" errors and such error shouldn't get process to be considered
successful.

libcontainer to manage /dev and /proc (#4945)
libcontainer already manages `/dev`, overriding task_dir - so let's use it for `/proc` as well and remove deadcode.
