feat: add ability to get console logs (#434)

[ADDON-73881](https://splunk.atlassian.net/browse/ADDON-73881)

As a smartx enjoyer, I want to get access to the browser console logs to
fail my tests if there are JS errors.

## Changes
- Add capability to track logs in Chrome
- Add a helper to access an array of logs


## Example of usage
```python
        severe_console_logs = get_browser_logs(ucc_smartx_selenium_helper.browser, log_level=LogLevel.SEVERE, log_source=LogSource.CONSOLE_API)
        assert not severe_console_logs, f"Unexpected severe console logs found: {severe_console_logs}"
```

Currently, this feature is only supported with the Chrome browser.
Analysis on adding support for other browser:
