[CT-3370] [implementation] ensure dbt retry works with unit tests

[graciegoheen]

Housekeeping

• I am a maintainer of dbt-core

Acceptance criteria

dbt retry re-executes the last dbt command from the node point of failure.

Once we finish swapping over the dbt unit-test command to dbt build and dbt test with selectors (#8979), let's confirm dbt retry still works.

If a unit test fails in a dbt test or a dbt build, dbt retry should re-execute that dbt command from the failed unit test.

• check that this works for dbt build and dbt test
• add integration tests

Impact to Other Teams

Will backports be required?

This appears to be working (in simple cases). I added an initial functional test for this in #9032:

dbt-core/tests/functional/unit_testing/test_unit_testing.py

Lines 172 to 179 in cc94269

	class TestUnitTestRetry(UnitTestState):
	def test_unit_test_retry(self, project):
	run_dbt(["run"])
	run_dbt(["unit-test"], expect_pass=False)
	self.copy_state(project.project_root)
	results = run_dbt(["retry"], expect_pass=False)
	assert len(results) == 1

Open question from refinement:

• how will this work given we have a separate manifest for unit testing

@graciegoheen I believe this was resolved by: #9032

test case here:
https://github.com/dbt-labs/dbt-core/pull/9032/files#diff-0f0c14a88170fc0b4f9e86ec195ef3df5a15801b97ccca70dfcefe1c58210832R108

I thought we changed the acceptance criteria to work on this ticket after we switched over the unit testing commands?

But if the test is enough then I’m good to close it!
