Hardcode Fleet-Manager CLI command registration

[SimonBaeumer]

Description

Hardcoding the fleet-manager CLI command registration instead of using the DI container registration.
This removes the need of reflection and cleans up error logs dramatically.
The DI container is still passed to all commands.
