ebos: tune the defaults of the high-level NewtonMethod parameters

Browse Source 
the intention is to abort more quickly if a time step is not going to
succeed and also to prevent the time step size to grow too quickly
again after it was reduced. Note that these parameters this patch only
changes the defaults, i.e., these paramters can still be specified at
runtime.
