* Fix issue that causes a new image store to be created at every start of ucloud-api. * VM Migration API call now takes hostname instead of host key. * StorageHandler Classes are introduced. They transparently handles things related to importing of image, make vm out of image, resize vm image, delete vm image etc. * Loggers added to __init__.py of every ucloud component's subpackage. * Non-Trivial Timeout Events are no longer logged. * Fix issue that prevents removal of stopped VMs (i.e VMs that are successfully migrated). * Improved unit handling added. e.g MB, Mb, mB, mb are all Mega Bytes. * VM migration is now possible on IPv6 host. * Destination VM (receiving side of migration of a vm) now correctly expects incoming data on free ephemeral port. * Traceback is no longer output to screen, instead it goes to log file. * All sanity checks are put into a single file. These checks are run by ucloud.py before running any of ucloud component.
