Add a new unit test to test max_available_extent namespace.
This feature is implemented by the following patches.

  kernel side:

    https://lists.01.org/pipermail/linux-nvdimm/2018-July/016732.html

  ndctl side:

On my test setup, this fails because the region returned is the 32M
one. This causes the namespaces requested to be 8M sized, which is too
small, and hence rejected (16M minimum).

The following jq query sorts it in descending size order and lets it
choose the 64M region:

	jq -r 'sort_by(-.size) | .[].dev'

Since these happen in a subshell, errors are lost.
Running in a subshell is fine, but we should test that the variables
weren't blank:

	test -n "$NS1"

And so on.

Hi Vishal,

Thank you for your review! I'll fix and send v3.

Thanks,
Masa
