"intelmqctl log" level selection does not work

[sebix]

With a bot that has level INFO set, the current and expected result of the commands is with intelmqctl log $bot 10 $level:

• (default/missing) Actual: All; Expected: All ✅️
• DEBUG Actual: Nothing; Expected: All ❌️
• INFO Actual: All info; Expected: All info and above ✅️
• WARNING: Actual: Info; Expected: Only warning, error and critical ❌️
• ERROR: Actual: Info; Expected: Only error and critical ❌️
• CRITICAL: Actual: Info; Expected: Only critical ❌️

The API/Manager is of course affected too. The selection 'ALL' doesn't work either.
