bump docker/docker, sirupsen/logrus v1.4.1

Full diff: https://github.com/sirupsen/logrus/compare/v1.3.0...v1.4.1

Fixes:

- Remove dependency on golang.org/x/crypto
- Fix wrong method calls Logger.Print and Logger.Warningln
- Update Entry.Logf to not do string formatting unless the log level is enabled
- Fix infinite recursion on unknown Level.String()
- Fix race condition in getCaller
- Fix Entry.WithContext method to return a copy of the initial entry

New:

- Add DeferExitHandler, similar to RegisterExitHandler but prepending the handler to the list of handlers (semantically like defer)
- Add CallerPrettyfier to JSONFormatter and `TextFormatter`
- Add Entry.WithContext() and Entry.Context, to set a context on entries to be used e.g. in hooks
- Enhance TextFormatter to not print caller information when they are empty
