[`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).
