feat: allow modifications to log levels using properties

[0utplay]

Motivation

CloudNet provides a logback configuration which works for most users. But if someone wants to change the log level of a single logger the user would either need to change the level for all loggers or override the whole configuration.

Modification

Added support for logbacks https://logback.qos.ch/manual/configuration.html#propertiesConfigurator which allows to set log levels using a simple properties file.

Result

Log levels can easily be changed by the user without replacing (and potentially breaking) the whole logback configuration.
