* Reduce possibility of circular dependency Just by adding an import for bus to anything in the helper dir, we would run into a circular dependency due to how things are structured. That means that we cannot set any events for unpacking or docker helper pulling an image. This commit tries to work around this by doing several things. - Remove full imports of the helper module by segmentating some modules into their own submodule, like docker or match so just using a small match function doesnt bring the whole module - Removing a simple function to check if a dir exists from importing the full helper module and instead write the function (5 lines) - Using logrus in the bus module instead of logger, which avoids a circular dependency Signed-off-by: Itxaka <igarcia@suse.com> * Add two new events for unpacking an image Both pre and post unpacking an image Signed-off-by: Itxaka <igarcia@suse.com>
