S3 and file logger -- change experiment folder name timestamp rounding

[martins0n]

🚀 Feature Request

Current approach uses timestamp with seconds like that 2022-09-16T17-20-46. In case of parallel experiment running result could be corrupted.

Proposal

We should add random posftix for example or add milliseconds

Test cases

Run multiple experiments in parallel. check for corruption. (it's just for local use. We shouldn't add such test case)
