[BUG] Journal as 'Python3' and not as WALinuxAgent

1. Section of the log where the error occurs.

The log identifier is not set to WALinuxAgent which can make troubleshooting issues more difficult:

Mar 22 10:02:23 sltestrhel9-2023-0217 **python3**[948]: 2023-03-22T09:02:23.944179Z ERROR Daemon Daemon Event: name=WALinuxAgent, op=UnhandledError, message=Traceback (most recent call last):

**Distro and WALinuxAgent details:**
- Distro and Version: RHEL9
- WALinuxAgent version: WALinuxAgent-2.3.0.2-3.el9.noarch

**Additional context**
log forwarding based on the identifier is easier and more reliable, also will help identifier issues faster.

Can this be improved?

Start with azurelinuxagent/daemon/main.py, especially the run and daemon paths shown in the log, and trace how the process name is supplied to journald. Check the existing logging or service configuration related to the WALinuxAgent identifier. Done means journal entries identify WALinuxAgent rather than python3 and the relevant tests or logging checks pass.
