Add multiarch specific fixes to the pipeline tests

Test code has many amd64 specific images.
Tests fail on non amd64 architecture because of that.
This code provides one place to keep multiarch
specific updates, separated for each architecture.

Multiarch utils do following:
- replace image names to arch specific ones whete it is applicable
- skip the tests, which fail for non amd64 arch now, based on test name
 and architecture
- skipping will be applied for e2e and examples tests
