[OE-core] [PATCH 2/3] lib/oeqa: add module for running tests outside of the build system

[Stefan Stanacar]

This script will run the exported tests outside of the build system.

Simplest way to test this is with a qemu image that you manually start.
For an already build image use this in local.conf:
TEST_EXPORT_ONLY = "1"
TEST_TARGET = "simpleremote"
TEST_TARGET_IP = "192.168.7.2"
TEST_SERVER_IP = "192.168.7.1"
Export the tests: bitbake core-image-sato -c testimage
Then: runqemu core-image-sato
And: cd build/tmp/testimage/core-image-sato
     ./runexported.py testdata.json

The contents of build/tmp/testimage/core-image-sato can be moved on another machine
as long as some paths are updated in the json.
The exported data contains paths to the build dir. We only care about DEPLOY_DIR/rpm (
if the rpm and smart tests are enabled), so running the tests on other machine
means that the user has to move the contents and call runexported with --deploy-dir PATH:
 ./runexported.py --deploy-dir /path/on/another/machine testdata.json
runexported.py accepts other arguments as well, see --help.
