xenapi: fix rootwrap

The xenapi root wrapper did not parse the "exec_dirs" parameter, so it
failed to execute the commands. This patch works around this problem by
parsing the "exec_dirs".

Remove unit tests that are no longer run.

A long time ago, quantum/tests/unit became the home for all unit
tests, but these ones in the Cisco plugin directory got left
behind. They have suffered bit-rot and need to be removed.

Also:
- Move the fake Nexus driver to new home.
- Filed new bugs to track the task of improving unit test coverage of
  Cisco plugin code.
