    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.
