Logs of a campaign

[jgaida]

It would be nice to have a log on the user side of what Cigri did during a campaign.
gridstats -c -f gives the state at a given moment but there is not much information about how we reach this state.

I'm thinking of something like this:

[timestamp] Prologue on cluster xxx
[...]
[timestamp] Submit job 1 on cluster xxx
[timestamp] Submit job 2 on cluster yyy
[timestamp] Event 15463: The job 1 on cluster xxx exited because of a working directory error. 
[timestamp] User fixed all events and jobs 1 is resubmitted (-r -f)
[timestamp] Submit job 1 on cluster zzz
[...]
