Removed EDP dependency on hive server

Currently EDP has two dependencies on hive:
1. get_hiveserver instance obtained by naming convention (hiveserver
   process name). E.g. for HDP plugin this doesn't work because process
   has other name (HIVE_SERVER)
2. there is get_hive_config_path method in plugin SPI. It tells where
   hive config is stored locally on hive server. EDP copies it into
   HDFS for each hive job

This CR removes both dependencies. Since we copy conf file to HDFS for
each job, we can copy it one time and reference to it. Location of
shared config file is hardcoded (like it is done for oozie share libs).
