[NOTICE] ENV changes from $MY_SQROOT to $TRAF_HOME

[Zhang, Yi (Eason)]

Hi All,

[TRAFODION-2388] was merged in today:
https://github.com/apache/incubator-trafodion/pull/869

It cleans up all 3 old environment variables ($SQ_HOME, $SQ_ROOT, $MY_SQROOT) 
and convert them into one ($TRAF_HOME).
So when your new changes need to use old $MY_SQROOT variable, please use 
$TRAF_HOME instead.

Thanks,
Eason
