Bug fixes and improvements
- Use defaults for logFileDirectoryPath and logFileRegex that work for Greengrass components that print to standard output (stdout) and standard error (stderr).
- Correctly route traffic through a configured network proxy when uploading logs to CloudWatch Logs.
- Correctly handle colon characters (:) in log stream names. CloudWatch Logs log stream names don't support colons.
- Simplify log stream names by removing thing group names from the log stream.
- Remove an error log message that prints during normal behavior.
