log: swap logrus functions with their equivalent on default logger

thaJeztah · thaJeztah · commit 0a7f2975efba · 2023-09-09T00:09:48.000+02:00
[`logrus.SetLevel()`][1], [`logrus.GetLevel()`][2] and [`logrus.SetFormatter()`][3] are all convenience functions to configure logrus' standardlogger, which is the logger to which we hold a reference in the Entry configured on [`log.L`][4]. This patch: - swaps calls to `logrus.SetLevel`, `logrus.GetLevel` and `logrus.SetFormatter` for their equivalents on `log.L`. This makes it clearer what `SetLevel` does, and makes sure that we set the log-level of the logger / entry we define in our package (even if that would be swapped with a different instance). - removes the use of `logrus.NewEntry` with directly constructing a `Entry`, using the local `Entry` alias (anticipating we can swap that type in future).
