Added create_hdfs_dir method to oozie edp engine

Adding abstract create_hdfs_dir to base oozie edp engine allows to
differenciate hadoop1 and hadoop2 implementations and use different
code for different hadoops. This is done to remove ugly hacks around
hdfs communication made to work with any hdfs implementation.
