Allow setting DEBUG log level on containers #260
Description
Reason/Context
As of today, we don't have an easy way to set the DEBUG log level on containers, which makes things difficult to diagnose in case of an issue or unexpected behavior.
But since microcks/microcks#1867 we now have an easy way to change the log levels.
Description
The goal of this feature is to allow users to set up more verbose log levels, enabling them to gain deeper insights into what's going wrong when retrieving the containers' logs by piping their output to specific consumers.
Implementation ideas
We can add either a withDebugLogs() or withLogsLevel(DEBUG) on the MicrocksContainer class. Calling this method before startup will allow to set the correct environment variables. We also need the same things on MicrocksContainerEnsemble for both the microcks and the microcks-async-minion containers.
