LU-1422 cray: Cray platforms set the initial connection value to high

LU-1422 cray: Cray platforms set the initial connection value to high

While testing imperative recovery it was observed that cray systems
had a noticable delay that did not happen on other systems. It was
discovered that the INITIAL_CONNECTION_TIMEOUT has set to a value
for the old Cray catamount systems which is not long valid and
now impacts recovery performace for both the IR and SR case. Also
this patch removes some catamount hacks from liblustre.
