This fixes an error in the devstack/functions
setup_develop call, which tries to cd to
$REQUIREMENTS_DIR, which is created in lib/infra

Move install responsibilities to domU

As we are moving forward to test XenAPI in the gate, it is necessary to
move dom0 related modifications to be performed from domU. For this
purpose, a new user is created, and that user should be used to talk to
dom0 from domU. This change creates that user, makes it possible for
dom0 to log in to domU with that account, and configure that account to
be able to talk down to dom0.

Also move several steps to the nova xenserver plugin:
 - dom0 plugin installation
 - create kernels and images directory
 - install console rotate script
 - configure a cron to execute console rotate script

Configuration changes:
    A new configuration option, DOMZERO_USER has been created, that
    specifies a user account that is configured to be able to do
    passwordless ssh to dom0.

Cleanup cinder-rootwrap support

cinder_rootwrap support in devstack handled a number of now-abandoned
use cases:

- no $CINDER_DIR/etc/cinder/rootwrap.d (old-style rootwrap)
- using oslo-rootwrap instead of cinder-rootwrap (abandoned experiment)

This change removes unused code paths and aligns
configure_cinder_rootwrap() with configure_nova_rootwrap().

Install glance images before starting Nova

The docker driver for Nova needs a registry service to be running.
It is being run inside a container using an image -- that image must
be downloaded. The registry service must be started via
nova_plugins/hypervisor-docker, but this is presently called
before Glance's image download.

The reordering is being done such that Glance may download the
registry image, but prior to starting Nova such that "hypervisor-docker"
may have an image downloaded and available to launch the registry.

This change should cause no negative effects on other hypervisors.

Split functions

Move shared and non-DevStack-specific functions to `functions-common`.  This is
a code move only with some updated comments.  The functions are now
sorted alphabetically within function groups, eg. all git-related functions
are grouped together.  The groups are listed at the top of the file.

'functions' sources 'functions-common' so no additional changes are required
for backward-compatability.

All functions shared with Grenade have also been moved.

functions-common was created from commit e0ed8ea038299952826b27a16753775472f108d8

Set DEFAULT_IMAGE_NAME for Docker hypervisor

This allows the tempest configuration to set the right
image for booting docker containers with Nova.

Since glance uploads are not yet integrated in devstack,
IMAGE_URLS remains empty.

Fedora repository.

Fix tee statement for catching tempest output

The use of exec and tee doesn't seem to be quite right, and was
unreliable in terms of catching the exit status of the tempest
test as well as not catching the output when things went wrong.

This changes the way we do the redirect and the tee to something
that should be more robust and seems to work reliably in testing.

Marconi fixes for precise

Fix a couple of problems found on Ubuntu:
* $MARCONI_DIR/etc/marconi/policy.json doesn't exist; removed the copy to /etc/marconi
* added a seting of nssize in /etc/mongodb.conf for Ubuntu
* restart the correct serice name on Ubuntu

Revert the tempest service name to marconi

This patch is to rollback the change introduced by
https://review.openstack.org/#/c/73100/. 73100 is no longer needed
because of the recent https://review.openstack.org/#/c/69497/.
Using 'marconi' as the service name will keep us aligned with the
naming convention used by other projects.

Optionally enable file injection

There is a patch up for nova right now that disables file injection by default.
This is a corresponding devstack change that only sets file injection options if
it is enabled in the devstack config.  This is good to keep around so that we
can easily turn it on for testing.

The nova change is id Icff1304fc816acc843f8962727aef8bbbc7bbaa3.
