[PATCH v2 1/3] oeqa: add OETestPriority decorator

["Konrad Weihmann" <kweihmann@outlook.com>]

This modifies an implicit default priority.
Can be used to move the test case either to the front
or to the end of the test suite.
Value can be between 0 and 99, implicit default is 50.
Lower values move are run at the beginning of the list,
higher values at the end.
Within a single priority ordering remains unchanged.

It enables use cases such as shutdown tests, which
should always run at the end of the overall test suite,
no matter what test suites/cases are set in the current
test suite list.

This avoids also using test suite naming hacks, such as
usage of zzz_foo_test.FooClass.test_foo to move it to
the end of the test suite list.
