28 persistent logs

Changed object_exists method to check if at least one object with partial name (job id) exists in the object storage instead of matching the whole name (which is problematic due to a random variable part of the file name.

Thanks for your PR!
Can you please describe what case this solves? Why does this need to be changed?

[vlerkin]

The situation: names of the log files were changed to random, the new format is jobID_logs_randomComponent. The problem with the random file names is that part of the logic that checks if a file was already uploaded to the object storage does not work properly for this situation, so the new logic that accommodates variable component in the file name was implemented. The new logic inside object_exists method checks if a list of objects with a particular partly name (job ID) exists in the storage.

Thanks for explaining 👍
(it's helpful if changes are not only understandable to those currently working on the code, but also in retrospect by others)
