Allow test suites to be configured individually. Moreover enable them to
implement their own custom configuration.
This solution adds some new complexity to DTS, which is generated source
code. In order to ensure strong typing, the test suites and their custom
configurations need to be linked in the main configuration class.
Unfortunately, this is not feasible during runtime as it will incur in
circular dependencies. Generating the links appear to be the most
straightforward approach.
This commit also brings a new major change to the configuration schema.
Test suites are no longer defined as a list of strings, like:
test_suites:
- hello_world
- pmd_buffer_scatter
but as mapping of mappings or strings:
test_suites:
hello_world: {} # any custom fields or test cases can be set here
pmd_buffer_scatter: all # "all" defines all the test cases, or
# they can individually be set separated
# by a space
Not defining the `test_cases` field in the configuration is equivalent
to `all`, therefore the definitions for either test suite above are
also equivalent.
Creating the __init__.py file under the tests folder, allows it to be
picked up as a package. This is a mypy requirement to import the tests
from within the framework.

Depends-on: series-32823 ("dts: Pydantic configuration")
Hello,
sending in a solution for the per-test-suite configuration issue.
This one took some thinking but I have given most of the motivations in
the commit body already. The docs are somewhat lacking but hopefully they
should be automatically tackled by the API docs generation.
Best,
Luca

and used by the test suite via the ``sut_node`` field.
+The test suites can also implement their own custom configuration fields. This can be achieved by
+creating a new test suite config file which inherits from ``TestSuiteConfig`` defined in
+``dts/framework/config/test_suite.py``. So that this new custom configuration class is used, the

+Finally, the test suites and the custom configuration files need to linked in the global configuration.
