Description

It adds a new system property, webdriver.edge.loglevel on EdgeDriverService.
It allows us to configure the log level in detail.

For example, if you use version 104.0.1293.63 Microsoft Edge WebDriver, you can choose one from ALL, DEBUG, INFO, WARNING, SEVERE, or OFF.

$ ./msedgedriver --help

  --log-level=LEVEL  set log level: ALL, DEBUG, INFO, WARNING, SEVERE, OFF

What this system property does is to make sure to specify the --log-level option like the others.

Detail: validation of given string

When users provide an invalid log level, MsEdgeDriver will be terminated due to an error; Invalid --log-level value.

$ ./msedgedriver --log-level=UNKNOWN
Starting Microsoft Edge WebDriver 104.0.1293.63 (7dd22b4a7f122e6953a166b0388edf494d716c7d) on port 9515

Invalid --log-level value.
Unable to initialize logging. Exiting...

I wondered if I should validate if a given value is valid, but I didn't implement it because I was concerned that support costs would be high. For example, it is an extreme case, but we might need to have a log level list for each version when MsEdgeDriver adds or removes log levels, etc.
