Changes in Apache Libcloud 2.0.0
--------------------------------
Common
~~~~~~
- Fix OpenStack drivers not correctly setting URLs when used with identity API, would default to 127.0.0.1 and service
  catalog URLs were not adhered to.

- Fix Aliyun ECS, Load balancer and storage adapters when using unicode UTF-8 characters in the names of resources
  in 2.0.0rc2 < it would fail as a MalformedResponseError, Python 2.7 element tree was raising a unicode error

- Refactor the test classes to use the full libcloud.http and libcloud.common.base modules, with Connection,
  Response all used with requests_mock. This increases our test coverages and catches bugs in drivers' custom
  parse_body and auth modules

- Rename libcloud.httplib_ssl to libcloud.http now that we don't use httplib
