               list_lookups_by_state("http://localhost:8081","_default_tier",False) 

 lookup_post(coordinator_url, tier, lookup name, mysql_jdbc, db_user, db_password, key_column, val_column, poll_min):  
    This function can be used to post the lookup into druid cluster with the given details
    example : lookup_post("http://localhost:8081","_default_tier","test_lkp","<jdbc url of the metastore database with port number>","<db user name>","<db password>","tst_key_col","tst_desc_col","10")
