* Use `ctx` rather than `context.TODO()` where available
* Further propagation of context
* Use `context.Background()` instead of `context.TODO()` where appropriate in tests
* Further remove `context.TODO` from tests
* Appease linter on parameter order
* 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

Spring cleaning!
A very mechanical cleanup using several linters (unused, deadcode,
structcheck). Build and tests still pass so no behavior should be
affected.
This commit aadds multiplexer library of SSH/TLS on the same
listener socket. The multiplexer detects the protocol by the first
3 bytes of the incoming connection and forwards wrapped
connection either to the SSH ot TLS listeners.
The library also supports PROXY line protocol
and wraps connection information with connection details
from the proxy line received by the server
