Merge configurations

Merge configurations

- changed temporarily HV-VES default log level to DEBUG as in current
implementation we are applying LogLevel defined in configuration file only
if we successfully retrieve one from configuration-module, which means
that inside of this module we are logging on default level (from logback
file). This should be fixed in future work
- reduced log level on SDK's CbsClientImpl as it's logging frequency was
too high
