Thanks for the PR! LGTM overall but the unit still needs fix.

Thanks for the update, only a small nit and this PR is good to be merged.
After #53475 has merged, we don't need pytest.mark.asyncio any more.
It would be nice to remove the mark and rebase again, thanks!

@NilsJPWerner Yes, this PR is nearly complete, but I don't have the right to merge the code. Still wait for approval to merge. |

Description
Addresses the issue where KubernetesPodOperator (KPO) logs always include a container name prefix, which can consume unnecessary horizontal space and feel redundant. This PR introduces two new optional parameters to
KubernetesPodOperator:log_prefix: A boolean to enable/disable the container name prefix in logs (default: True).log_formatter: A callable to fully customize log output format, overriding log_prefix if provided.This allows users to either disable the prefix or define a custom log format, improving log readability and flexibility.
