Add ability to prefix e2e tests from CLI

[kmontemayor2-sc]

Scope of work done

Do this so we can more easily differentiate between different CI/CD runs :)

Where is the documentation for this feature?: N/A

Did you add automated tests or write a test plan?

Updated Changelog.md? NO

Ready for code review?: NO

A slight design choice I made here when implementing this:
A fixed prefix keeps jobs sorted/grouped --> filterable by identity, while a configurable suffix cleanly captures the variable part (environment, version, run) without disrupting any of that. (Similar to how naming files / tables / etc - prefixes are static and suffixes change)

Thus, Id pref if we instead had something like "override_suffix" or something.

What is this for btw? We just want to differentiate jobs that are run by a single person i.e. adding ${whoami} as part of the name?

Suggested alternative: Btw, Since we have support for name_suffix already, we can try adding something like following to our e2e_test.yaml

tests:
  cora_nalp_test:
    name_suffix: "_on_${now:}_${oc.env:BRANCH_NAME}"
    task_config_uri: "gigl/src/mocking/configs/e2e_node_anchor_based_link_prediction_template_gbml_config.yaml"
    resource_config_uri: "${oc.env:GIGL_TEST_DEFAULT_RESOURCE_CONFIG,deployment/configs/e2e_cicd_resource_config.yaml}"
