Witek Bedyk e883b5bcda Move data_points to repository class
data_points_class can be now declared as a List or a Dictionary. The
latter is used when writing measurements per tenant. This refactoring
avoids creating the dictionary and then chaining again its values in
case of ElasticSearch and Cassandra databases or if db_per_tenant option
is disabled. The change also fixes the events pipeline.
