- Use a dummy nodename instead of OS hostname
- Inline toString() function
- Use backticks to wrap expected patch
- Remove redundant test name from error logs
These are based on recommendation from
[staticcheck](http://staticcheck.io/).
- Remove unused struct fields
- Remove unused function
- Remove unused variables
- Remove unused constants.
- Miscellaneous cleanups
Used T.Run API for kubeadm tests in app/phases/*
This should improve testing output and make it more visible
which test is doing what.
