Pulp

Hi, I ran into an issue when running `pulp-admin rpm repo publish run --repo-id $MY_REPO`.

I've attached admin.log and curated server_calls.log for analysis.

I managed to get past this though, with a one line patch guided by the traceback in the admin.log (pull request under way, in case you want that..:).
Not sure if it is the right thing to do, but it seemed to work..

```
diff --git a/client_lib/pulp/client/commands/repo/status.py b/client_lib/pulp/client/commands/repo/status.py

step.processed = step_details[reporting_constants.PROGRESS_NUM_PROCESSED_KEY]
-        step.details = step_details[reporting_constants.PROGRESS_DETAILS_KEY]
+        step.details = step_details.get(reporting_constants.PROGRESS_DETAILS_KEY, None)
if not step.details:
    step.details = None
```
