This function returns the directory containing the configuration
files. It takes into an account the evironment variables as follows:
- If SCYLLA_CONF is defines - this is the directory
- else if SCYLLA_HOME is defines, then $SCYLLA_HOME/conf is the directory
- else "conf" is a directory, namely the configuration files should be
looked at ./conf
