This function has been shared at least kwapi and all Telemetry projects including ceilometer, aodh, panko and gnocchi. As a generator, it produces sequence of keypairs for nested dictionaries. It seems to be good moving it to the common shared code. So add an initial dictutils and tests for it. Change-Id: Ibd7c2ce4ef9c2608910b26169a804eb463759c7f
