StoreGateSvc add option to dump the Arena stats

StoreGateSvc add option to dump the Arena stats

Adding something like this in postExecx

cfg.getService("StoreGateSvc").DumpArena = True 

In a test (Overlay) I see

@ssnyder can you take a look at this? Not 100% if all the placements make sense. The clearStore I picked as is where we call reset . then due to locks wanted to have it somehow separate .

@jchapman I think now some of the things we see make a bit more sense ...
