fix: 1ES pipeline fixes

[hallvictoria]

Description

1ES security fixes
- Removed index-url for test-pypi
- Refactored dummy container key into pipeline env variable

1ES pipeline changes
- Deleted GitHub workflows
- Added public build tests: unit
- Added official build tests: docker consumption, docker dedicated LC, E2E, unit
- Refactored E2E tests to all run together
- Removed redundant steps from building / packaging scripts (PublishAndBuild task is not allowed)
- Added scheduled and PR-based integration test workflow that runs unit, E2E, and LC tests
- Added scheduled docker consumption and dedicated test workflow
- Added manual core tools & custom image test workflow

Test fixes:
- Numpy_func: to be compatible with latest major release
- Test_logging: path changes when running in ADO
- httpv2 debug logging: skipping as debug logging seems to work different in ADO (TODO: fix later)
- docker tests: installing correct dependencies to run the tests, installing base extension in container, moving httpv2 tests to separate class to help with flakiness
