This change makes each step of the kolla deployment aware
of the port database was configured to listen on.
It defaults mariadb_port to database_port.

Due to poor planning on our variable names we have a situation where
we have "internal_address" which must be a VIP, but "external_address"
which should be a DNS name. Now with two vips "external_vip_address"
is a new variable.

This corrects that issue by deprecating kolla_internal_address and
replacing it with 4 nicely named variables.

kolla_internal_vip_address
kolla_internal_fqdn
kolla_external_vip_address
kolla_external_fqdn

The default behaviour will remain the same, and the way the variable
inheritance is setup the kolla_internal_address variable can still be
set in globals.yml and propogate out to these 4 new variables like it
normally would, but all reference to kolla_internal_address has been
completely removed.

Throughout the project overtime some of these file permissions have
changed to have an executable bit. They should not have this bit set.

sudo requires a tty to function by default on centos. Instead of
tweaking the sudo conf we can just add a tty. This has the added
advantage of making the containers more friendly if you have to
`docker exec -i <container> bash` into them.

Ansible 1.9.2 contains the fix needed for docker-py >1.2.0

This is needed for some gate reasons, but it is also a good version
bump because it fixes a few issues with delegate_to.

This brings Kolla images inline with FHS and should make finding
locations of things more consistent and reliable with the linux world
at large.

VIP takes time (10-30 seconds) to appear on one of network nodes.
Ansible does not wait for the VIP and starts keystone. The latter
fails because it cannot connect to database thru the VIP.

If ip_vs is not loaded keepalived will enter a restart loop.  To fix that
load ip_vs module every time we start the container.

This patch checks that haproxy is alive and running. It does this by
using socat to talk to the haproxy socket. That socket will only
respond successfully when haproxy is active and functional.
