[tyr-worker] feat: trying to avoid 'logs forwarding' to fail the entire process

[woshilapin]

Let's try to protect us against any failure triggered by the log forwarding. Note that this PR is a best effort, but probably doesn't fix https://navitia.atlassian.net/browse/NAV-1653.

About the original ticket, after more searching, we think we now have a good explanation of what is going on (but it's hard to verify for sure).

The best hypothesis is:

• "log forwarding" apply the .decode operation per chunks (calling read_async() and therefore .read())
• the chunk contains multi-bytes characters like é and one of the chunk ends with only half of one of this multi-byte characters
  • note the error message which is [...]donn\xc3', 4095, 4096, 'unexpected end of data')
  • 4096 = 2¹² which looks pretty much like an ideal chunk size
  • the \xc3 is missing something to represent données (in the logs, we have a full version of it a line above donn\xc3\xa9es)

If the hypothesis is correct, then #3880 should have already fixed the problem. But this PR should also prevent a bit more.
