#1260

• increased timeouts for sent jobs (which are needed if the jobs take long time to deserialize on slave)
• added DeleteJob to ClientService
• made optimizer actually Pause instead of Stop when stop is called explicitly (so they can be resumed later)
• temporarily disabled job-abortion from server because it aborted jobs which took too long to deserialize on slaves (this issue needs to be investigated)
• reduced locking of engines on slave so that the deserialization does not block heartbeats

#1347

• worked on HiveEngine
• added test project for HiveEngine
