add async fire-forget/check functionality
Adding support for A10 Networks slb server, slb service-group, slb virtual-server
PEP8 Compliant except needed long lines and better exception handling
Fix the docs for glance_image.endpoint_type

The endpoint_type option was added in version 1.7,
so the docs need to state this.  Also the the description
is too brief.
Fix typo: `active` -> `activate`
Always return a list even if its empty.
portage: Add support for --changed-use

The `--changed-use` flag is an improvement over `--newuse` because it
does not trigger rebuilds for USE flag changes that would not affect the
installed package. Its use is generally recommended over `--newuse`.
