dlt-daemon: Lower log level of logs not to output unintentional warning (#58)

* dlt-daemon: Lower log level of several logs not to output unintentional warning

Change log level of several logs from WARNING to INFO.
1. User FIFO cannot be opened because the FIFO does not exist
   --> This case can happen if DLT user app is one-shot
2. Runtime configuration file (dlt-runtime-application.cfg / dlt-runtime-context.cfg)
   cannot be opened
   --> This case can happen in normal use case.
