Disable cinder with ironic

Cinder doesn't currently work with ironic as volumes cannot yet
be attached to baremetal nodes. This is something that may be
available in the K series. For now, though, so that we can work
on enabling the tempest API and scenario tests with ironic, we
need to disable cinder.

Rename subunit_log.txt to testrepository.subunit

Subunit is not a text protocol - it tunnels itself in stdout, but
that is not the same thing. The .txt extension leads to bad headers
from Apache:

wget -S http://logs.openstack.org/.../logs/subunit_log.txt.gz
HTTP/1.1 200 OK
Date: Sun, 31 Aug 2014 23:40:07 GMT
Server: Apache/2.2.22 (Ubuntu)
Vary: Accept-Encoding
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/plain

which are clearly bogus - and worse cause wget and curl to treat this
as a plain text file - so they apply line ending transformations to it
which breaks the contents. Some browsers are smarter when one does
'save link' - but all in all its a poor thing to present a binary
object as text.

Don't be confused by the lack of Content-Encoding on the object - thats a
separate issue.

Always set DATA_DIR

I noticed this when debugging [1]

devstack is intended to set $DATA_DIR to $DEST/data by default, but
currently it does that *before* reading localrc so it always uses its
default $DEST value of /opt/stack.

The code in devstack-gate.sh directly chowns /opt/stack/data/tempest
for the tempest user; this is required for tempest to be able to write
out lock-files.  This currently works due to the above, but if
devstack is fixed to correctly locate DATA_DIR under DEST, the chowned
path is now wrong.

The issue is made more confusing as the extant code explicitly sets
DATA_DIR if running grenade (why is not really explained in the
original change [2]).

The solution is to always explicitly set DATA_DIR to $BASE/data.
Since this is /opt/stack/data, the existing devstack (which
essentially assumes this path) continues to work.  A fixed devstack
will use the explicitly set path and continue to work.

There is no need to explicitly set SWIFT_DATA_DIR as that appears to
be a work-around for an old bug [3]

Switch to static content for glance upload test

glance is able to fetch an image from a given url.
Previously the dashboard main page was used as image,
this change sets it a static image, in order
the have less gate issue.

Any url could be used which does not requires authentication.

Handle @s in log file names by renaming them

Rabbit log files are bad and use @ in the filename. Replace @ with _at_
to prevent the log server from 404ing on these files.

Bump BUILD_TIMEOUT for both Ironic drivers

BUILD_TIMEOUT is currently bumped from its default 196s to
300s for the Ironic agent_ssh deploy driver.  Enabling parallel
Tempest testing of the pxe_ssh fails periodically due to build
timeouts, likely due to concurrent deployments generating lots of
i/o.  This bumps the timeout for all Ironic jobs.

Remove Nova v3 API test configuration

Nova v3 API has disappeared in Juno cycle, and we don't test the API
now on the gate since If63dcdb2d05aa0fab0b6848a1248b6678f1ee9ad .
This patch removes Nova v3 API test configuration.

Remove TESTR_FULL option for running tempest

The TESTR_FULL option was added back when tempest was running by
default with nosestests serially to test using testr in parallel.
However, this migration happened >1yr ago and the testr-full job is
just a duplicate of the regular full now. This commit removes the
option of running with TESTR_FULL to prevent confusion.

This adds the kernel info to the setup log which is often useful for

don't use screen for grenade

now that the process stop pieces of devstack work much better,
it's not clear that we need to actually use screen to stuff in
the service starts / stops.

We should try to do this without screen.

This allows us to specify that a particular set of libraries should be
