Subject: [PATCH v4 4/6] kunit: add is_init test attribute
Add is_init test attribute of type bool. Add to_string, get, and filter
methods to lib/kunit/attributes.c.
Mark each of the tests in the init section with the is_init=true attribute.
Add is_init to the attributes documentation.
Signed-off-by: Rae Moar <rmoar@...gle.com>

Changes since v3:
- Move the attribute from kunit_attributes to a suite field.
