Steps to reproduce

• Adjust the source code to display log log.timestamp instead of log.message
• Add print("next_start_time", next_start_time) at the end of the while loop (resp = self._api_client.logs.poll in runs.py)

Run the following with the file/AWS/GCP logging.

type: task
name: print-numbers

commands:
  - |
    python -c "for i in range(1, 100001): print(i)"

$ dstack logs print-numbers | sort | uniq -c > print-numbers.txt

Actual behaviour

The polling function across all storages (file/GCP/AWS) uses start_time as a way to paginate logs.
In case too many event share the same timestamp, it truncates the output.

Expected behaviour start_time for pagination.

It should always use a unique token:

• AWS/GCP - support their own
• File logging may use line number from the file.

The polling function should NOT use
