Info to match when looking for cinder in the service catalog.
Possible values:
* Format is separated values of the form:
<service_type>:<service_name>:<endpoint_type>
Related options:
* endpoint_template - Setting this option will override catalog_info

If this option is set then it will override service catalog lookup with
this template for cinder endpoint
Possible values:
* URL for cinder endpoint API
e.g. http://localhost:8776/v1/%(project_id)s
Related options:
* catalog_info - If endpoint_template is not set, catalog_info will be used.
"""),
cfg.StrOpt('os_region_name',
help="""
Region name of this node. This is used when picking the URL in the service
catalog.
Possible values:
* Any string representing region name
"""),
cfg.IntOpt('http_retries',
default=3,
min=0,
help="""
Number of times cinderclient should retry on any failed http call.
0 means connection is attempted only once. Setting it to any positive integer
means that on failure connection is retried that many times e.g. setting it
to 3 means total attempts to connect will be 4.
Possible values:
* Any integer value. 0 means connection is attempted only once
"""),
cfg.BoolOpt('cross_az_attach',
default=True,
help="""
Allow attach between instance and volume in different availability zones.
If False, volumes attached to an instance must be in the same availability
zone in Cinder as the instance availability zone in Nova.
This also means care should be taken when booting an instance from a volume
where source is not "volume" because Nova will attempt to create a volume using
the same availability zone as what is assigned to the instance.
If that AZ is not in Cinder (or allow_availability_zone_fallback=False in
cinder.conf), the volume create request will fail and the instance will fail
the build request.
By default there is no availability zone restriction on volume attach.
