[PATCH V2 39/46] nvmftests-tests: add a test to scan host ctrls and ns

[Chaitanya Kulkarni]

From: Chaitanya Kulkarni <chaitanya.kulkarni at wdc.com>

This adds a new test to scan all the host ctrls and ns.
This can be used as a template in future tests where scanning
of the host subsystem is needed. e.g. adding a new ns after
connecting to the target and verifying that newly added ns
on target is appearing on the host in a timely manner.
