oeqa/core: Add base OEQA framework

case: Defines OETestCase base class that provides custom
    methods/attrs defined by the framework.
    Every OETestCase instance contains a reference to the test
    data (d), the test context (tc) and the logger.
    Also implements _oe{SetUp,TearDown}Class for make special
    handling of OEQA decorators and validations.

runner: Defines OETestRunner/OETestResult with support for RAW
    and XML result logs.

exception: Custom exceptions related to the OEQA framework based
    on class OEQAException.
