ETCH-280 Updating CAPU and adapting logger interface

This patch upgrades to CMake dependency to capu 0.13.0.
Due to this upgrade the logger interface needs to be changed
to use the new logging mechanism provided by CAPU 0.13.0.
In order to achieve this the EtchLogger has been extended by
a new macro called ETCH_LOG_<LOGLEVEL> in order to add an
abstraction from the CAPU logger.
