This change adds puppet hieradata settings which disable IPv6
autoconfiguration and accept_ra by default on all interfaces.
When IPv6 is used, the interfaces are individually enabled and
configured with static IP addresses.
The networking on the compute host needs to be completely
separate from the tenant networking, in order to safeguard the
compute host and isolate tenant traffic. This change disables
IPv6 autoconfiguration and acceptance of RAs by default on
interfaces unless specifically enabled.
Without these settings, IPv6 is enabled on all interfaces, as well
as autoconfiguration and accept_ra, so when the compute host
creates a bridge interface for the router (qbr-<ID>), the
compute node will automatically assign an IPv6 address and will
install a default IPv6 route on the bridge interface when it
receives the RAs from the Neutron router.
The change to turn off autoconfiguration means that interfaces
will not self-assign an IPv6 address, and the change to not accept
RAs is a security hardening feature. This requires that a
static gateway address be declared in the network environment
in the parameter ExternalNetworkDefaultRoute. Alternately, sysctl
can be modified to change the accept_ra behavior for specific
interfaces.

This change adds the TripleO Heat Parameters and Puppet hieradata
to support setting the MTU for Neutron tenant networks. A new
parameter, NeutronTenantMtu is introduced, and this gets used for
the NeutronDnsmasqOptions and in Puppet hieradata.
NeutronTenantMtu is also used in the Puppet hieradata for both the
compute and control nodes. Two values are set:
nova::compute::network_device_mtu
which sets /etc/nova/nova.conf: network_device_mtu = <NeutronTenantMtu>
neutron::network_device_mtu
which sets in /etc/neutron/neutron.conf:
network_device_mtu = <NeutronTenantMtu>
finally, the NeutronDnsmasqOptions parameter becomes a str_format
that maps the NeutronTenantMtu onto the DHCP options,
so a default of 'dhcp-option-force=26,%MTU%' would be formatted to
'dhcp-option-force=26,1300' if NeutronTenantMtu were 1300.
This will set dnsmasq to serve an MTU via DHCP that matches the
NeutronTenantMtu:
/etc/neutron/dnsmasq-neutron.conf:dhcp-option-force=26,1300
Typically, you would change all three of these settings to use small
or jumbo frames in VMs. When using tunneling, NeutronTenantMtu
should be set at least 50 bytes smaller than the physical network
MTU in order to make room for tunneling overhead.
Note that this change does not support setting the MTU on veth
interfaces if veth patches are used to br-int instead of OVS
patches.

Currently the permissions for the CA file that is injected (if the
environment is set), doesn't permit users that don't belong to the group
that owns the file to read it. This is too restrictive and isn't
necessary, as the certificate should be public.
This is useful in the case where we want a service that can't read the
certificate chain (or bundle) to be able to read that CA certificate.
This is the case for the MariaDB version that is being used in CentOS
7.1 for example.

We were incorrectly wiring the rbd user to the relevant glance
module parameter, making it was impossible to customize the
rbd user when using an external Ceph.

Changed the heat-docker-agents namespace to use the namespacing
specified in the environment file, which reduces modifications required
on the user when using a local registry.
Changed the start agents script to handle using a local registry both
with a namespace and without.

This hieradata key, neutron::agents::ml2::ovs:bridge_mappings was
missing a : before bridge_mappings causing the value to be blank in
/etc/neutron/plugins/ml2/openvswitch_agent.ini even if a value had been
specified.

With a properly configured undercloud the DNS is fine. We can remove
the 8.8.8.8 dns setting.

As per conversation in [1], these settings should have probably never
been there.

It turns out the linters rename was a bit premature[1]. Use the
current standard pep8 name so we don't need custom jobs in the
gate to run this test on proposed changes.

For both HA & non-HA scenarios, switch puppet-keystone configuration to
be run in a WSGI process instead of eventlet.
WSGI is the way to go for scaling Keystone, moreover, eventlet won't be
support in next OpenStack releases.

During high load, the default limit of the kernel connection tracking
table (65536) is often too low, resuling in error messages such as:
kernel: nf_conntrack: table full, dropping packet
This patch increases the limit to 500,000.
Since the nf_conntrack kernel module is not always loaded by default, it also
adds a mechanism to load kernel modules via hieradata using the kmod puppet
module. In order to express the needed dependency in puppet that kernel modules
are loaded before sysctl settings are applied, the Exec resources tagged with
'kmod::load' are specified in a resource collector to express that that Exec
resources with the tag should run before Sysctl resources.

This change will set a common value for 'host' across all
controllers. We missed to do so for the NFS backend previously.
It will still be possible to set a different per-backend 'host'
value by providing it via ExtraData.

The maximum payload size of the return signal from a Heat software
deployment is 1MB, and the output of yum starts breaking this limit at
~1000 packages to update - which is not an atypical number. To prevent
this, pass the -q (quiet) option to reduce the amount of output to a
manageable level.

When we utilise images for deployment, the iSCSI initiator name
is not unique, leading to problems with live migration. This
patch simply updates the iSCSI initiator name to a unique ID
randomly generated by iscsi-iname.
