In order to avoid name conflicts with WorkerTaskContext
- renamed WorkerTask::log to WorkerTask::log_message
Note: Methods have different fuction signatures
Also renamed WorkerTask::warn to WorkerTask::log_warning for
consistency reasons.
Use the task_log!() and task_warn!() macros more often.
API like in PVE:
GET .../info => current cert information
POST .../custom => upload custom certificate
DELETE .../custom => delete custom certificate
POST .../acme/certificate => order acme certificate
PUT .../acme/certificate => renew expiring acme cert
