Don't clear host_state_map when scheduling
host_state_map was added to scheduler for the purpose of caching latest
host_state in memory for scheduler. With this cache, scheduler has the
latest host_state (e.g. free_capacity, allocated_capacity, etc) of hosts
even hosts haven't reported their updated status to scheduler.
Unfortunately, this cache is flushed when scheduling pulling all available
volume services from DB in current implementation, which is a bug.
This change remove the host_state_map.clear() so that scheduler is able to
maintain an up-to-date (well, mostly) view of all volume services in memory.
Also, added code to remove non-active host from the cache every time when
scheduler handles a new request. Multi-line docstrings in cinder/scheduler/

GlusterFS: Increase snapshot delete job timeout to two hours
Increase the timeout for Nova snapshot delete operations from ten
minutes to two hours. This helps prevent Cinder from terminating
operations prematurely that are still being processed by Nova.
It is not uncommon for snapshot delete jobs to run for longer than
ten minutes depending on the size of the snapshot and speed of the
storage backend.
This will be followed up with a more robust mechanism to keep track
of snapshot job progress as a later effort.
This patch changes the way the config options are

settings together by fabric name, we look for
fabric groups based upon the fc_fabric_names.

Storwize/SVC: Change volume copy task to async
If Cinder crashes during a migration or retype (where data is moved and
the operation can take a long time), the storage ends up with multiple
copies of the same volume which requires storage admin intervention.
This patch maintain a list of pending operations which is backed up in
admin metadata, and a periodic task reviews the list and removes volume
copies whose copy operation completed. When Cinder comes up, check the
admin metadata and rebuild the list.
Creating FC connections was not working due to several issues:
1. The lsfabric command in the Storwize/SVC omitted the delimeter and so
the output was not correctly parsed by the driver.
2. In some cases comparisons of WWPNs were not case insensitive - ensure
we compare lower-case WWPNs.
3. If the host supplied extra information in the connector (e.g. iSCSI
initiator name in case of an FC setup, or FC WWNNs/WWPNs in an iSCSI
setup), the driver would try to make those host mappings on the storage
too. This could lead into unwanted behaviour and confusing error
messages (for example, in an FC setup reaching the maximum number of
iSCSI mappings).
In addition, unit tests weren't properly testing FC - instead they were
always testing iSCSI due to an error in parsing extra_specs. This patch
fixes that error and the unit tests as well.
These changes must all be made together for unit tests to pass.
Allows automated zone lifecycle management in the attach/detach
entry points of the volume manager for FC volumes (when fabric
zoning is enabled). Zones are configured automatically as part
of the active zone set in the FC SAN to provide a more flexible
and secure way of controlling access. FC zone manager enables
SAN vendors to add support for pluggable implementations.

Add x-openstack-request-id to cinder responses
x-openstack-request-id is the common header name for request ID going forward.
Currently, only glance and neutron return this header. Using the request_id
middleware is a convenient way to ensure this header is in the response. We will
also be using the middleware to generate the request ID.
The ID will be generated by the middleware and is inserted into the request
environment. The current code generates the request ID in the constructor of
RequestConext; with this change, the ID is generated beforehand and passed in to
the RequestContext constructor. Not much different here: a request ID is
generated and is available for use in the handling of the request.
On the response end, the middleware is again used, this time to attach the
x-openstack-request-id header, using the value of the generated request ID. The
current code attaches the x-compute-request-id header.
This change is a necessary step toward logging the mapping of request IDs across
OpenStack services.
