flaky tests: consistent logging (#4849)
* Update logrus package to fix data races
* Introduce a logger that uses the test context to log the messages so they are output if a test fails for improved trouble-shooting.
* Revert introduction of test logger - simply leave logger configuration at debug level outputting to stderr during tests.
* Run integration test for e as well
* Use make with a cap and append to only copy the relevant roles.
* Address review comments
* Update integration test suite to use test-local logger that would only output logs iff a specific test has failed - no logs from other test cases will be output.
* Revert changes to InitLoggerForTests API
* Create a new logger instance when applying defaults or merging with file service configuration
* Introduce a local logger interface to be able to test file configuration merge.
* Fix kube integration tests w.r.t log
* Move goroutine profile dump into a separate func to handle parameters consistently for all invocations
