Sets up a Sirupsen/logrus logger for the Axiom API.
As always when using the Axiom API, you should make sure to set up Axiom params in the env:
// Export `AXIOM_TOKEN`, `AXIOM_ORG_ID` (when using a personal token) and
// `AXIOM_DATASET` for Axiom Cloud.
// Export `AXIOM_URL`, `AXIOM_TOKEN` and `AXIOM_DATASET` for Axiom Selfhost.
