Cinder backup requires iSCSI volume and host mount for backing
any iSCSI volume, not only from LVM backend. 'enable_iscsid' is
a catch-all setting for all iSCSI backends that also runs
necessary iSCSI client on the same host.

When using cinder lvm backend storage driver, lvcreate will load dm_*
linux modules when need. So /lib/modules is needed by cinder_volume
container.

Currently Cinder configuration hard-codes tgtadm as the only
iSCSI management utility. tgtd and tgtadm are older tools to
manage iSCSI volumes. Newer versions of Linux distros use
targetcli and kernel based iSCSI facilities (LIO) and can be
a preferred way for some users.

Currently if Ceph is used for Cinder volumes the only choice of
backup driver is Ceph. It should be possible to use any backup
driver for any volume type, e.g. iSCSI volumes can go to Ceph
based backup storage.

cinder-volume will be hanged if rados_connect_timeout is disabled. And
no error message will be thrown. Disable timeout is not a good idea.
This patch sets the rados_connect_timeout to 5.

Booting from volume require cinder's ceph client secret now. Move cinder
before nova in site.yml, because nova depends on cinder ceph client key
now.

We do not use *.j2 filename pattern in custom config folder. Add
nfs_shares without .j2 extension for consistency. And do not remove the
.j2 extension file for back compatibility.

At present, cinder/nova/glance/gnocchi relative containers's
ceph.conf aren't be merge from user custom's config.
In some condition, we should add extra parameter to custom's
ceph.conf, for example:rbd_default_features = 1.
So, it is necessary to use merge_configs instead of template.

Cinder can be configured to support either
lvm or ceph backend. Using both backends only enables lvm
as the ceph backend configuration is combined
with the lvm backend part via elif code.

This commit brings necessary configuration and container start-up
options to use two popular backends for backup - nfs and swift.
Both drivers support incremental backups and should work with any
cinder volume backend.

Currently, policy.json is put in
"{{ node_config_directory }}/{{ service_name }}"
in target nodes.
Relocation policy.json to "{{ node_config_directory }}/{{ item }}"
with item is corresponding service compoment config directory.
Currently, the policy.json is copied to all services, but it
should be reviewed and left only in neccesary service
(at many cases, only API service needs that).
Redundant files will be removed in follow up patchset.

Nova and Cinder used a list of glance api servers - this list
does not provide a proper high availability because the servers
are connected at random without recalling who is failed last
time. E.g. out of three controllers with a failed first one nova
and cinder can try connection to the first controller because of
random / shuffled choice of the glance server. A proper solution
is to use VIP that connects to alive server from the beginning.
Also as workaround one could significantly increase max number
of retries in configuration files in hope that a random function
will choose a healthy glance server sometime - not a good choice.

Using the `when` conditional on a `with_` loop gets evaluated on each
loop iteration and will not skip a task entirely. Use the `skip`
attribute to ignore errors in this scenario but only `skip` when
`enable_cinder_backend_nfs` is not enabled. If it is enabled the
`nfs_shares` file should be required and this task should fail if it
does not exist.

Allow cinder-volume, nova-compute and nova-libvirtd to be configured to
use NFS. In order to mount and work with NFS shares, several containers
needed the NFS packages installed during build time.
One somewhat significant change is the addition of an explicit bind
volume for nova-compute that has shared mounts enabled.
According to docker-run(1), the shared mount propagation flag can only
be specified for bind mounted Docker volumes and not named volumes.
In an NFS setup, cinder-volume mounts the NFS shares so that it can
create and manage the Cinder volumes. When a new instance is created
with a Cinder volume or a Cinder volume is attached to an existing
instance, nova-compute mounts the Cinder volume from the NFS share for
nova-libvirtd. In order for nova-libvirtd to then see those Cinder
volumes the shared mounts flag must be enabled for the Docker volume.
Remove the rpcbind container as it is only necessary for operators who
are using NFSv3 or lower. There is no known need for this currently
however, this container can be added in the future should an operator
require it.
