    HAWQ-587. Set GUC 'default_hash_table_bucket_number' value dynamically

    When doing 'hawq init master/cluster', we will check command option '--default_hash_table_bucket_number'
first, if it was not given by user, then we use the value defined in 'hawq-site.xml'.
    
    If no option given and not defined in 'hawq-site.xml', we will calculate a number out
for 'default_hash_table_bucket_number' base on segment number and the up limit value 'hawq_rm_nvseg_perquery_limit'.
