[Bug 1333219] [NEW] Virt driver impls don't match ComputeDriver base class API

 

Public bug reported:

There are a number of problems where the virt driver impls do not match the API defined by the base ComputeDriver class.
For example

 - Libvirt:  Adds 'SOFT' as default value for 'reboot' method but no other class does
 - XenAPI: set_admin_passwd takes 2 parameters but base class defines it with 3 parameters in a different order
 - VMWare: update_host_status method which doesn't exist in base class & is never called in entire codebase
 - All: names of parameters are not the same as names of parameters in the base class
 - ...more...

These inconsistencies are functional bugs in the worst, or misleading to
maintainers in the best case. It should be possible to write a test
using the python 'inspect' module which guarantees that the sub-class
APis actually match what they claim to implement from the base class.
