Allow custom root labels

Makes the localboot element aware of the custom root fs labels
added in I596104d1a63b5dc6549e8460a1ae3da00165ef04 for
diskimage-builder.  That change must merge before this one.

Hash instance-id instead of expecting specific format

In versions of cloud-init prior to 0.7.5,
/var/lib/cloud/data/instance-id was something of the form
i-########.  Our mysql-common element used that ######## bit to set
the mysqld server_id.

In cloud-init 0.7.5, and probably above, the instance-id file is a
uuid instead, which means there is no numeric part for us to use as
the server_id.

To address this, I'm hashing the instance-id and using that
value instead of one pulled from the id itself, which should work
for arbitrary formats of the id.  There is some tiny chance of
hash collisions with this method, but the server_id will allow
2 ^ 32 - 1 different values, so the odds of that happening are
extremely small.

RHEL SELinux custom policy for neutron-ns-meta

neutron-ns-meta is denied connectto on unix_stream_socket on RHEL.

Fedora selinux-policy has the correct fix. That fix needs to be
applied to RHEL. We need this custom policy until it is applied.

Install static element files

Several elements want to install static files. Some do this using the
"os-apply-config" directory, which means these files are unnecessarily
rewritten every time os-refresh-config triggers. Others put files in a
"files" dir and manually script the installation from an install.d
script.

This patch offers a more convenient "static" directory. Files placed in
here will be rsynced into the image.

Add initial svc-map support

This patch incorporates the svc-map patch[1] into other
elements by integrating svc-map into the os-svc-install
element.  This patch adds the -a option to select svc-map
instead of the default of map-services.  The -a option
enables a phased transition from map-services to svc-map
usage throughout the rest of the elements.

haproxy global maxconn is less than default maxconn

The current global maxconn is hard-coded to 4000 and the default
per-service maxconn is 8000. As a result we have a potential
denial of service attack with a single service using up the
global limit.

This patch makes the global maxconn and the per-service maxconn
configurable. The default global maxconn is left at 4000 and the
default value for the default per-service maxconn is set to a much
lower value. With this change, both per-service default and
individual service maxconn settings are configurable.

Note the default per-service level setting of 150 was chosen on the
basis of haproxy handling 20 services, leading to 200 connections
per service. A value lower than 200 was chosen to allow wriggle room
for specific service maxconn levels to be set higher than others.

Revert "Install static element files"

Needs more thought about how to ensure files are owned by the correct user. The only way which occurs to me is a manifest file and I'm not sure that fits within the "convenience budget" compared to installing files with install.d scripts.

This reverts commit 00b7e98af1e8b7f14895736e4df079757624948e.
