Valeriy Ponomaryov 48221b0f4c Reuse 'periodic_task' from oslo_service
Remove Manila code related to 'periodic_tasks' and reuse it from 'oslo_service'
library.

Also, add call of parent's '__init__' method for 'manila.db.base.Base' class.
It is required for proper work of multiple inheritance where this class is
inherited. And remove it from inheritance by 'manila.network.neutron.api.API'
class as redundant.
