> Issue Type: Bug

>
> Currently {{SimpleDBProviderBackend}} doesn't retry the authorization
> properly. Problems are:
> # It retry count is hard coded. Always retries once
> # No wait time between before retries
> # The method calls itself recursively, which could causes stack overflow if
> retries too many times
> # If an exception happens in
> {{SentryPolicyServiceClient.listPrivilegesForProvider}}, then
> {{policyServiceClient}} won't be closed, which could cause resource leak.
