S3 orphaned objects monitoring

[NikitaUnisikhin]

• Decomposition _clean_object_storage. Create object_storage/utils.py
• Create ch-monitoring orphaned-objects
• Added future tests for new functionality

Questions:

• Monitoring has a clear output format, so it is impossible to use code from cli, since there are many logs. It’s worth separating logic from logging as much as possible. Maybe write a decorator to disable logs (simple solution)? Or should we do even more decomposition and increase the modularity of the code?

The more comments you have, the better :)
