GetExecutorLossReason to use a smaller timeout parameter

   right, so to clarify I think you are say yes if you set askTimeout separate 
it also fixes the problem, correct?
   
   So my concern is that you are fixing this in a single location, I think 
there are other places that could have the same issue, although the question is 
whether those are recoverable or not.  
    In this case it is recoverable because its just trying to get the loss 
reason and if it doesn't it can go on just fine and the AM will restart and 
connect back to the driver.
   My other concern here is that we are breaking what the configs actually do. 
This is no longer just the asktimeout or network timeout, its 0.95 times one of 
those. Which is inconsistent with what is documented and  everywhere else. Let 
say I set ask timeout different from network timeout, now you are decreasing 
the ask timeout even more then what I set it to.
   
   so I'm wondering if you can just set the ask timeout globally different or 
if that causes other issues?
