Fix stale volume list for NetApp 7-mode ISCSI driver
While contacting filer through DFM in order to create volume from
snapshot, the operation may fail with an error "No entry in LUN
table for volume". Although the LUN representing the volume was
created on the filer, the LUN list was not refreshed in time, which
caused an error. This fix handles this situation for creating
volume from snapshots.

Scality SOFS is a network filesystem mounted with FUSE, with most

configuration file as driver options, the Scality volume driver mounts
SOFS, and then creates, accesses and deletes volumes as regular

Allow create_volume() to retry when exception happened
Due to the fact that certain volume back-ends cannot easily report
simple total_capacity_gb/free_capacity_gb for their internal
implementation complexity, scheduler is updated to let those back-ends
who report unclear capacity pass capacity filter, thus there is chance
create_volume() request would fail. In a more general case, when a
volume back-end failed to serve create_volume request for whatever reason
it'd be good that we have a mechanism to 'retry' the request.
So the idea is when volume manager catches the exception from
driver.create_volume() call, it checks if the request is allowed to be
rescheduled (requests that are not: clone volume and create volume from
snapshot while 'snapshot_same_host' option is true), it composes a new
request back to scheduler with additional information to mark this specific
back-end has been tried (so that scheduler may choose to skip this back-end
if needed). Scheduler is (filter scheduler only, simple and chance
scheduler is not supported) is updated as well so that it only retry
scheduler_max_attempts times. In order to skip/rule out previously tried
back-ends in next schedule task, a new RetryFilter is added.
Changes:
1) volume RPC API create_volume() is updated with new parameters
to save original request information in case rescheduling is needed.
This bumps volume RPC API to 1.4.
2) implementation of create_volume() method in volume API is
refactored in order to distinguish if a request is allowed to
do reschedule (i.e. currently create volume from source volume
bypasses scheduler, not rescheduling is allowed).
3) add reschedule functionality in create_volume() of volume
manager so that it's able to send the request back to scheduler.
4) add schedule_max_attempts config option in scheduler/driver.py
5) add RetryFitler
6) change scheduler_driver default option to FilterScheduler
