  - Merge "Optimize storage schema for Redis driver"
  - Optimize storage schema for Redis driver
    
    The original Redis driver stored each tracing event under its own key,
    as result both list and get operations required a full scan of the database.
    With this patch traces are stored as Redis lists under a key equal
    to trace id. So list operation iterates only over unique trace ids
    and get operation retrieves the content of a specified list. Note that
    list operation still needs to retrieve at least 1 event from the trace
    in order to get a timestamp.
    
    Performance test is executed with 1000 traces each consisting 1000 events:
     * existing driver:
       * write: 48 sec
       * list:  41 sec
       * get:   3.6 sec
     * optimized driver:
       * write: 44 sec
       * list:  4.1 sec
       * get:   0.01 sec
