* 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.
Remove individual config.py used by every component and put them into single config.py ucloud/config.py
Use /etc/ucloud/ucloud.conf for Environment Variables
Refactoring and a lot of it
Make ucloud repo a package and different components of ucloud a subpackage for avoiding code duplication.
Improved logging.
1. User can now use image name instead of image uuid when creation vm.
For Example, now user can create an alpine vm using the following
command
```shell
ucloud-cli vm create --vm-name myvm --cpu 2 --ram '2GB' \
--os-ssd '10GB' --image images:alpine
```
2. Instead of directly running code, code is now placed under a function
main and is called using the following code
```python
if __name__ == "__main__":
main()
```
3. Multiprocess (Process) is used instead of threading (Thread) to update
heart beat of host.
4. IP Address of vm is included in vm's status which is retrieved by the
following command
```shell
ucloud-cli vm status --vm-name myvm
```
