When a service connects to the database VIP from the node hosting this
VIP, the resulting TCP socket has a src address which is by default
bound to the VIP as well. If the VIP is failed over to another node
while the socket's Send-Q is not empty, TCP keepalive won't engage and
the service will become unavailable for a very long time (by default
more than 10m).
To prevent failover issues, DB connections should have the src address
of their TCP socket bound to the IP of the network interface used for
MySQL traffic. This is achieved by passing a new option to the
database connection URIs. This option is available starting from
PyMySQL 0.7.9-2.
We use a new intermediate variable in hiera to hold the IP to be used
as a source address for all DB connections. All services adapt their
database URI accordingly.
Moreover, a new YAML validation check is added to guarantee that new
services will construct their database URI appropriately.

Heat now supports release name aliases, so we can replace
the inconsistent mix of date related versions with one consistent
version that aligns with the supported version of heat for this
t-h-t branch.
This should also help new users who sometimes copy/paste old templates
and discover intrinsic functions in the t-h-t docs don't work because
their template version is too old.

The cell v2 setup requires the transport url for nova. We need to
provide mysql with the rabbit connection information so that it can it
when setting up the cell information.

run-os-net-config.sh only allows for limited customization of the
network configuration in config.json. Namely, it only customizes the
bridge_name and interface_name.
This will likely not be sufficient for all use cases. This patch adds a
generic network_config_hook bash function that will be called if it is
defined. The function is an entry point for deployers to write custom
code to further influence run-os-net-config.sh.
A possible alternative approach would be to pass the server resource
into the NetworkConfig template. That would allow running arbitrary
SoftwareDeployments on the server before NetworkDeployment is executed.
However, the interface of NetworkDeployment is likely still not as
flexible as this approach as the inputs are hardcoded in the role
template files (role.role.j2.yaml), which are not meant to be modified
by deployers.
The immediate use case for this work is using os-net-config in our
multinode CI jobs where we need to create vxlan tunnels between the
nodes and we need to know the local private IP of each node for the
tunnel endpoint. As the IP is different for each node, it's not a
parameter we could specify in the templates.

Currently the description of CI matrix is defined
in tripleo-ci, but the services for each scenario
lives now in THT. This submission moves this table
to the repo in which the configuration is defined.

This enables the deployer to dynamically add nova metadata to the
servers based on the output of service profiles that implement the
metadata_settings key in the role_data output for the profiles.
One can set an implementation via the OS::TripleO::ServerMetadataHook
resource, which currently is set as OS::Heat::None. So, because of
the default implementation, if left untouched it actually does
nothing.
Currently, besides the list, which is metadata_settings, this hook also
takes the name of the node that it's setting the metadata for.
This is useful for nova vendordata plugins that can parse said metadata.

This script is meant for CI and it deploys an instance of FreeIPA.
This instance is needed for deploying TLS everywhere and will serve as
the CA. The parameters relevant to this instance will then be passed to
the overcloud deploy command.

In order to call commands that need to be run on a single node, we
create a new per-service variable that will contain the first node of
each role containing the service.

Custom role deployments were not working when ODL API was on a different
node due to firewall rules blocking traffic. This patch adds the
missing rules for the REST communication to ODL (8081 by default), OVSDB
connection (6640), and OpenFlow protocol (6653).

ODL username and password are already present in the OpenDaylightApi
service. However, when moving the OpenDaylightApi service to its own
custom role, the Controller/Compute nodes no longer have access to these
hiera values. This patch adds them also to the OpenDaylightOvs service.

This patch updates the endpoint map for Zaqar websockets
so that we use ws (or wss for SSL) instead of the http varients.
This should help resolve protocol issues when trying to make
connections to the websocket API.

In the freeipa-enroll.yaml, it can be the case that the node has been
enrolled (via a cloud-init script); in this case, the OTP and the
FreeIPA server are optional. However, we still need to get a kerberos
ticket, which is the last step of this script, since this ticket is what
certmonger will use to request the certificates in subsequent steps.

It turns out the puppet-mistral change this depends on broke
introspection, so we need to back it out for now.
This reverts commit ed029e5bf279945e82bff8766af4093856a7ac6a.

This switches to using overcloud-full as the OS image for
containerized compute. It includes the following changes:
- install docker, until this change lands
I1eab2a6de721c8f3c21c7df0019f2d4d1cc3775f
- agent image pull has been removed. This avoids a race between docker
starting and the current call to pull. This relies on "docker run"
to do the initial pull and leaves open the option of some other
prefetch mechanism to do the initial pull
- rely on unit Conflicts= to ensure heat-docker-agents and
os-collect-config do not run at the same time
- tweaks to host bind mounts
- removal of commands which only apply to atomic

Currently when the docker environments are invoked, every node has the
boot script run which replaces os-collect-config with the heat-agents
container. This should only be happening on Compute nodes currently,
and each role will be converted to heat-agents one at a time.
This change implements a role-specific NodeUserData resource and uses
that mechanism to run docker/firstboot/install_docker_agents.yaml only
on Compute nodes.
Change-Id: Id81811dbcaf0e661c3980aa25f3ca80db5ef0954

These ensure that software configuration tasks are not re-run when the
heat-agents container is restarted.
