DatabaseCampaign: abstract campain for interaction with MySQL Database

Browse Source 
The DatabaseCampaign interacts with the MySQL tables that are created
by the import-trace and prune-trace tools. It does offer all
unfinished experiment pilots from the database to the
fail-clients. Those clients send back a (by the experiment) defined
protobuf message as a result. The custom protobuf message does have to
need the form:

   import "DatabaseCampaignMessage.proto";

   message ExperimentMsg {
       required DatabaseCampaignMessage fsppilot = 1;

       repeated group Result = 2 {
          // custom fields
          required int32 bitoffset = 1;
          optional int32 result = 2;
       }
   }

The DatabaseCampaignMessage is the pilot identifier from the
database. For each of the repeated result entries a row in a table is
allocated. The structure of this table is constructed (by protobuf
reflection) from the description of the message. Each field in the
Result group becomes a column in the result table. For the given
example it would be:

    CREATE TABLE result_ExperimentMessage(
           pilot_id INT,
           bitoffset INT NOT NULL,
           result INT,
           PRIMARY_KEY(pilot_id)
    )
