Add naive implementation of user password check by calling su command.
Also change some authentication method to require username to be string
instead of optional string
The issue appears in case if versions ar the same (e.g. rebuild); in
this case printer doesn't increment version as builder does.
Also util has been renamed to utils, keeping backward compatibiltiy
* implement log storage at backend
* handle process id during removal. During one process we can write logs from different packages in different times (e.g. check and update later) and we would like to store all logs belong to the same process
* set package context in main functions
* implement logs support in interface
* filter out logs posting http logs
* add timestamp to log records
* hide getting logs under reporter permission
List of breaking changes:
* `ahriman.core.lazy_logging.LazyLogging` has been renamed to `ahriman.core.log.LazyLogging`
* `ahriman.core.configuration.Configuration.from_path` does not have `quiet` attribute now
* `ahriman.core.configuration.Configuration` class does not have `load_logging` method now
* `ahriman.core.status.client.Client.load` requires `report` argument now
