silvacarloss 57edcbd1da Fix pagination does not speed up queries bug
This patch modifies the database api layer to fix the pagination
slowness bug, which causes a delay while the administrator tries
to list shares using the `--limit` option.
This change was tested in a very busy environment with 800 shares.
Before the change, the operation took about 25 seconds to be
finished. Now, the operation takes about 3 seconds in the same
environment.

When the OpenStack administrator has a busy environment that contains many
shares, the list operation with `--limit` parameter was taking too long to
respond. This lag has now been fixed. See the `launchpad bug 1795463
<https://bugs.launchpad.net/manila/+bug/1795463>`_ for more details.
