This commit sets the max microversions on the ocata branch so that
tempest doesn't try to run tests that require a newer api version.

There's a race condition when a client makes a request "at the same
time" the HTTP connection is being closed by Apache because the
`KeepAliveTimeout` is expired.

This is explained in detail and can be reproduce using
https://github.com/mikem23/keepalive-race or
https://github.com/JordanP/openstack-snippets/blob/master/keepalive-race/keep-alive-race.py

Just disable KeepAlive to fix the
('Connection aborted.', BadStatusLine("''",)) error we are seeing.

This commit switches devstack to use the published qcow2 cirros image
instead of the AMI version. Using AMI was mostly a historical artifact
dating pretty far back, but in the real world no one really uses AMI
images with openstack clouds. This change reflects that and also
enables tempest ro remove its deprecated config options for using AMI
as a fallback on misconfiguration (which was just there to support
devstack's defaults)

Currently placement api section will be configured on controller
only if service n-cpu is running. It breaks multi node setup.

On stable branches, we are supposed to hard code the extension list of
what API extensions are available when we branch the project so that
test cases against new features will be skipped. However, we didn't do
this on Ocata release.

Use pip_install_gr so we get the version pinned by requirements.  The
depends-on is an example of where we're trying to pin to workaround
issues.

Calling enable_kernel_bridge_firewall inside a
container, devstack will crash because it tries to
load a kernel module by calling 'sudo modprobe' on
net.bridge.

When variables use the 'declare' directive, it is by default a local
variable. While other variables have global scope.

For example:
   declare -A AN_ARRAY   # local in scope
   foo=1                 # global in scope

This causes errors to occur as some of the variables will be local only
and others will be global.

Update the code, as appropriate, so that variables using the 'declare'
directive also include the '-g' flag to have them also be global. Not
every instance of a declared variable has been updated.

For the latest qemu-kvm, you have to use the qemu-kvm-ev package,
which is based off the qemu-kvm-rhev package, which is explained in
[1] but you probably can't read it.  The gist is, that qemu-kvm-rhev
is a later build of kvm that is incompatible with the base version
provided.  qemu-kvm-rhev is only provided with the RHV (ovirt) and
RHOS (openstack) products.  CentOS rebuilds this package as
qemu-kvm-ev as part of it's virtualisation SIG.

I9a972e3fde2e4e552f6fc98350820c07873c3de3 has bumped up the minimum
qemu version to 2.1.0.  It seems there is a an issue (bug #1668164)
where having the qemu-system package installed gets picked up if
installed, and reports the incorrect version to nova, causing failure.

This removes the installs from files/rpms/nova as it is all being done
in function-libvirt.  We only install the qemu-kvm-ev package on
centos and remove the old work-around.

Since https://review.openstack.org/#/c/438325 landed
it only works for Centos 7, but not for other
RHEL-based distributions: Virtuozzo and, probably, RHEV.

Both of above have own version for qemu-kvm package: qemu-kvm-vz and qemu-kvm-rhev,
accordingly. These packages provide "qemu-kvm", like qemu-kvm-ev,
and, when you call "yum install qemu-kvm", they replace the default OS package.

Was using the '-ne' integer comparison operator to compare UUID
values. This caused error messages like:

/opt/stack/new/devstack/lib/tempest: line 226: [[: dfae26ac-1780-4677-902d: value too great for base (error token is "902d")

Change it to use '!=' string comparison operator
