Adding a test surface header to cron tests

[lucyking140]

This identifies cron test queries as test results instead of queries with an "unknown" surface in autopush, which helps to differentiate between actual queries that cannot be identified and these test cases. The tests are run in autopush, so changing them could make it easier to recognize regressions before the are deployed.

Summary of Changes

Hello @lucyking140, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request aims to enhance the clarity and effectiveness of cron-based integration tests by implementing a dedicated surface header. This change allows the system to accurately identify and categorize cron test queries as distinct test results, rather than generic 'unknown' queries. The primary benefit is improved visibility into test outcomes within autopush, which will facilitate quicker recognition and resolution of regressions, ultimately bolstering the reliability of deployments.

Highlights

• New Surface Header: A new constant, CRON_TEST_SURFACE, has been introduced to specifically identify queries originating from cron-based integration tests.
• Test Query Identification: Integration tests in adversarial.py and nodejs_query.py are now updated to include the CRON_TEST_SURFACE header in their HTTP requests, ensuring these queries are correctly categorized.
• Improved Regression Detection: By explicitly tagging cron test queries, the system can now differentiate them from 'unknown' queries in autopush, which will help in earlier and more accurate detection of regressions before deployment.
• Submodule Updates: The import and mixer submodules have been updated to their latest respective commits.

Code Review

This pull request adds a x-surface header to cron test queries, which is a good improvement for identifying and tracking these requests. The implementation is correct. I've suggested a small refactoring to improve maintainability by creating a shared constant for the header dictionary. This will reduce code duplication and make future changes easier.

[gemini-code-assist]

To improve maintainability and avoid duplicating the header dictionary construction, consider defining a constant for the cron test surface header, similar to TEST_SURFACE_HEADER. You can then use this constant in adversarial.py and nodejs_query.py.

Suggested change

	CRON_TEST_SURFACE = "cron-tests"
	CRON_TEST_SURFACE = "cron-tests"
	CRON_TEST_SURFACE_HEADER = {SURFACE_HEADER_NAME: CRON_TEST_SURFACE}

[gemini-code-assist]

To improve maintainability and centralize header definitions, it's better to define a CRON_TEST_SURFACE_HEADER constant in shared/lib/constants.py and import it here. This avoids importing CRON_TEST_SURFACE and SURFACE_HEADER_NAME just to construct the header.

Suggested change

	from shared.lib.constants import CRON_TEST_SURFACE, SURFACE_HEADER_NAME
	from shared.lib.constants import CRON_TEST_SURFACE_HEADER

[gemini-code-assist]

By using a predefined CRON_TEST_SURFACE_HEADER constant, you can simplify this call and ensure consistency across different parts of the codebase that need to send this header.

          headers=CRON_TEST_SURFACE_HEADER,

Response to all of these comments: I just used the test surface header instead -- figured I don't actually need a separate cron test header
