Gorka Eguileor da5ecebb33 Add support for collect-timing option ...

When we run "cinder help" we can see that there is a --collect-timing
option:

  --collect-timing Collect per-API call timing information.

This is a keystone session option that we are not currently acting on
from a user perspective.

This patch adds support for this option, and we'll be able to see the
timing in a similar way as we do with OSC:

$ cinder --collect-timing api-version
+------+---------+---------+-------------+
| ID   | Status  | Version | Min_version |
+------+---------+---------+-------------+
| v3.0 | CURRENT | 3.66    | 3.0         |
+------+---------+---------+-------------+
+--------+------------------------------------------------+----------+
| method | url                                            | seconds  |
+--------+------------------------------------------------+----------+
| GET    | http://192.168.121.243/identity                | 0.003591 |
| POST   | http://192.168.121.243/identity/v3/auth/tokens | 0.016649 |
| GET    | http://192.168.121.243/volume/                 | 0.004012 |
| GET    | http://192.168.121.243/volume/                 | 0.004543 |
+--------+------------------------------------------------+----------+

The patch formats the "elapsed" time attribute into seconds and renames
the column to "seconds" to make it more user friendly similar to OSC.
If we didn't it would look like 0:00:00.003744
