Prior to this it would download Go, setup the environment, then (maybe)
download Go again.
I renamed verify_go_version to be internal and fixed all callers.
- Added scripts for update and verify
- golang AST code for scanning and fixing imports
- default regex allows it to run on just test/e2e.* file paths
- exclude verify-import-aliases.sh from running in CI jobs
