[HBase] Implement events on HBase

In this change events are written into HBase and read from it.

For this purpose were implemented several methods:
1. record_events --- store events into HBase
2. get_events, get_event_types, get_trait_types and get_traits --- get events
from db.

Add new filters in mock HBase part, that were used in new methods.
