New configuration for Tomcat

• The Hadoop configuration directory needs to be added as the environment variable HADOOP_CONF_DIR and it has to be added to the web application's classpath.

• The environment variable can be added in <tomcat-root>/bin/setenv.sh, e.g. HADOOP_CONF_DIR=/opt/hadoop.

• To add the Hadoop configuration directory to the application classpath,
  in the file <tomcat-base>/conf/catalina.properties, append to the key shared.loader the hadoop conf dir, e.g. shared.loader="/opt/hadoop".

• Update env variable and application classpath as follows: <tomcat-base>/bin/setenv.sh. Add export SPARK_CONF_DIR=/opt/spark/conf
  /conf/catalina.properties
  Set shared.loader=/opt/spark/conf,/opt/hadoop_{environment} (It's important that /opt/spark/conf is before /opt/hadoop)
