Enable log file support

[JenySadadia]

Closes https://github.com/kernelci/kernelci-project/issues/334

Enable multiple log streams for Logger.

Create a file handler to dump logs to files. Use stream and file handlers for all the pipeline services to redirect logs to both the streams including stdout and log file. Update the logger config file.

Staging seems working and creating log files for pipeline services:

@nuclearcat Let me know if the file naming convention needs to be tweaked.

@nuclearcat We also need to add some kind of purge service that will discard the log files older than some decided number of days. Otherwise, It will create storage issues on VM.
