Just search in the path where python searches for modules.
Let's use python for searching, it knows the exact rules.

Add XenServer to GetDistro's logic

This is primarily to satisfy the expectations of various scripts that os_*
variables are defined, and will result in a distro similar to "xs6.1.0-59235p"

Added functions for get a ip on an instance

The cause of some gating failure looks like
because of getting ip address on instance.
However current exercise didn't log the return value.
In this commit, we add get_instance_ip function with
error hanlding support, and apply it on the execise.

Fix 'olso' typo in lib/oslo

This enables commit If92073be5a431840701c952a194e63a7c452c9ca
for cleaning up potentially installed older oslo.config. Here are
its original details.

If the user had oslo.config installed prior to us setting up the
oslo.config out of git they can get themselves into this very funny
situation where pip doesn't see oslo.config 1.1.x, however some
packages might. This manifests itself as a user error trying to
start nova-api which uses DeprecatedOption, not in oslo.config 1.1.x

Because of the funny state pip is in, you can't uninstall oslo.config.

So in these situations, if we see old oslo.config in the filesystem,
pip install / uninstall it to ensure that everyone ends up using the
git version instead.

To reduce the amount of user confusion, do this on every
install_oslo for a while, which we can purge after Havana ships.

Fixes: bug #1213089
Echo service start failures.

* functions: Previously screen_it would log service start failures by
touching a file, this isn't very useful when working with Jenkins.
Switch to echo'ing that a service failed to start and pipe that through
tee so that we can keep the old behavior of touching a file (note this
behavior is slightly modified and the touched file will now have
contents).

turn out usb_tablet for libvirt

This patch turns out usb_tablet for the libvirt nova.conf file.
When usb_tablet is turned on, qemu will poll for usb events and
this causes CPU usage even when the qemu is idle.
