[OE-core] [PATCH 09/32] scripts/oe-test: Add new oe-test script

[Aníbal Limón]

The new oe-test script will be use to run test components with
one single script.

The oe-test script search for test components inside meta/lib/oeqa,
the test components needs to implement OETestContextExecutor inside
context module in order to be supported by oe-test.
