Fixes bug 1284073 For pollster-originated samples related to instances, we apply a mapping to the user metadata so as to ensure that there are no embedded periods in metadata keys and also to exclude any metadata not matching the configured reserved namespace. Now this logic is also applied to user metadata for samples derived from instance-related notifications in order to avoid failures when persisting these data in mongodb.
