Handle two exceptions causing sync_patron_activity job to fail (PP-1838)

Description

Handle PatronAuthorizationFailedException and RemoteIntegrationException so they do not cause the sync_patron_activity job to fail.

The PatronAuthorizationFailedException that we are getting come mostly from the Enki collection. This appears to happen when the patron doesn't have any loans for Enki items.

The RemoteIntegrationException errors that we are seeing are mostly 504 responses coming back from Overdrive. These responses tend to come in waves, so I think it makes sense to do a few retries to see if we can successfully perform a sync.

Motivation and Context

When looking at setting up alerting for failing celery tasks, I saw that a large number of tasks were failing. In the last week I saw these failures:

Task Name	Exception	Count
patron_activity.sync_patron_activity	PatronAuthorizationFailedException	1719
patron_activity.sync_patron_activity	RemoteIntegrationException	231

Since these errors are mostly unavoidable, we don't want the job to fail because of them.
