How to set environment variables in saunter

[thirumal rao]

Hi,

 I am using cx_Oracle module to query an oracle DB for some data validation. For this cx_Oracle to work, I've to set the environment variables 

export ORACLE_HOME='/Users/xyz/oracle/instantclient_11_2'

export DYLD_LIBRARY_PATH=$ORACLE_HOME

export LD_LIBRARY_PATH=$ORACLE_HOME

What could be the best way to do it using saunter framework ?
