- Removes the hard-coded magic number of 60 seconds allowing users to choose the period that they require. - Standardise on strings for DictOpt dict keys. When loaded from a config file, the DictOpt keys are parsed as strings, which was conflicting with the default integer dict keys. This caused the periodic engine to silently fail to load when configured via a config file. - Remove unused variable Story: 2006783 Task: 37313 Change-Id: Ibd61c45fc1ade37022150d34a5b00c56fdf69814
