[~liming01] and [~doli] does this JIRA need to be targeted for
"2.0.0.0-incubating" release? If not, we should change the Fix Version to
"backlog" or another release. Please update the JIRA Fix Version field soon so
"2.0.0.0-incubating" is not blocked.

All of below functions are useless:
gp_distributed_xacts__
gp_max_distributed_xid
gp_distributed_xid
gp_transaction_log
gp_distributed_log
However, some of them may be referred by ORCA module, (i.e.
orca/scripts/log_runner/installcheck-workload.sql). And also we need refactor
the code about distribute transaction in the future. So I would like to
postpone this task.
