Code Issues Proposed changes

Change default glance_num_retries to 3

Browse Source 
Previously, the default value of glance_num_retries is 0. It means
that the request to glance is issued only one time. However, other
components' client retries the request when it fails.
To reduce an unnecessary exception and failure, we should increase
the default value to 3.

The default value of the configuration option, ``glance_num_retries``,
has been changed to 3 in this release. Its former value was 0.
The option controls how many times to retry a Glance API call
in response to a HTTP connection failure, timeout or ServiceUnavailable status.
By this change, Cinder can be more resilient to temporary failure and continue
the request if a retry succeeds.
