[PATCH v6 00/10] dts: add hello world test case

["Juraj Linkeš" <juraj.linkes@pantheon.tech>]

Add code needed to run the HelloWorld testcase which just runs
the helloworld dpdk application.

The patchset currently heavily refactors this original DTS code needed
to run the testcase:
* The whole architecture has been redone into more sensible class
  hierarchy
* DPDK build on the System under Test
* DPDK eal args construction, app running and shutting down
* Optional SUT hugepage memory configuration
  The optional part is DTS either configuring them or not. They still
must be configured even the user doesn't want DTS to do that.
* Test runner
* Test results
* TestSuite class
* Test runner parts interfacing with TestSuite
* The HelloWorld testsuite itself

The code is divided into sub-packages, some of which are divided
further.

There patch may need to be divided into smaller chunks. If so, proposals
on where exactly to split it would be very helpful.

v5:
Documentation updates about running as root and hugepage configuration.
Fixed multiple problems with cpu filtering.
Other minor issues, such as typos and renaming variables.

v6:
Moved utility functions into different files, mainly to remove util.py's
dependency on settings.py, but also better code organization.
