Fix bugs for Huawei driver

This fixes two bugs for Huawei iscsi driver.
(1)If firstly we map LUN 1(just not LUN 0) to host,we can also
find LUN 0 mapped,whose device path is '-'.Then we will failed
to map a real LUN 0.So,we avoid mapping LUN 0 to host by setting
every volume's host LUN ID larger than 0,instead of generating it
automatically.
(2)Check valid size of resource pools when creating snapshot and
make sure it larger than 1 GB.

Switch all uses of 422 response code to 400.

The 422 response is normally only for WebDAV, and these types of
errors should normally return a 400 code, HTTPBadRequest. This
commit goes through all the remaining 422 codes and changes them
to 400 responses.

Fix 3PAR driver hiding existing host error

This fixes a problem with the 3par drivers where creating
a 3par host was failing but there was no message.  The driver
would fail to find the host after the creation failed and the
log entry would show that the host didn't exist.   The real
error was failing to create the host.

Count Snapshots towards volume/gigabyte quotas.

Cinder has quotas and limits for volume-count and Gigabytes used,
however we were only counting volumes against these quotas.

This change introduces a snapshot-count limit and also counts
snapshots against this Gigabytes quota allowed for a Tenant.
