Code Issues Proposed changes

Update export location retrieval APIs 

Update the export location retrieval APIs for shares and share
instances to do the following:

1. Restore the API-to-view-builder calling convention of
index-->summary and show-->detail. In so doing, modify which
values are returned by the list commands (currently, all but
the timestamps). The admin context from the request determines
whether the admin-only values are returned.

2. Report the UUID field from the export location table as
'id' to be consistent will all other objects returned via the
Manila REST API.

3. Add the preferred flag to the output of the API. Drivers
can report preferred:True or preferred:False in their export
location metadata, and this standard flag will be returned
via the REST interface, like this:

+-------------------+--------------------------------------+
| Property          | Value                                |
+-------------------+--------------------------------------+
| is_admin_only     | False                                |
| uuid              | df828d44-0b04-47fa-8ee5-516ffc199ca7 |
| share_instance_id | 1b40e873-331e-4e1c-ab53-38ec95b3bfcc |
| path              | 10.0.0.100:/share_1b40e873           |
| created_at        | 2016-02-18T21:12:51.000000           |
| updated_at        | 2016-02-18T21:12:51.000000           |
| preferred         | True                                 |

2.13
----
Add 'cephx' authentication type for the CephFS Native driver.
2.14
____
Added attribute 'preferred' to export locations. Drivers may use this
field to identify which export locations are most efficient and should be
used preferentially by clients. Also, change 'uuid' field to 'id', move
timestamps to detail view, and return all non-admin fields to users.
