As a part of the community goal [1], we should replace rootwrap in
favor of privsep.
Although the latest codes don't have a dependency on rootwrap for now,
but it might be happened to introduce a task with root privilege after.
In addition, there are some complex mechanism embeded in Tacker such as
in setuptools or configs under `etc/`. It's hard to drop and restore
them again. So, keep the mechanism active.
In this update, two methods used for tests are implemented in
`tacker/privileged/linux_cmd.py`, but can be used for general purpose.
For the test, it's also including rootwrap for backward compatibility
which will be removed in a future update. It also updates required
libs as bellow for oslo.privsep 2.4.0.
- eventlet>=0.30.1
- msgpack>=0.6.0
- oslo.service>=2.5.0
