This enables golangci-lint via build tags for integration tests (this should have been done long ago!), and fixes the linting errors. Two tests were updated to reduce flakiness: * apply config: wait for nodes to issue "boot done" sequence event before proceeding * recover: kill pods even if they appear after the initial set gets killed (potential race condition with previous test).
