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.

Haproxy often breaks mysql connections that results in
"MySQL server has gone away" or similar because of 1 minute
timeouts. Instead the timeouts should be not less than mysql
connections timeouts - in most cases set to 3600s by default
by OpenStack projects.
