Description

1. Implement adding a entry into gp_configuration_history when segment' status is changed, so that users can know the reason of status change by querying this catalog table.
A cleanup function is needed when user decides to clear this table.

2. remove failed_tmp_dir and failed_tmp_dir_num columns in gp_segment_configuration. add a "description" column to show the reason of this segment is down.

3. merge YARN mode and NONE mode status.

postgres=# select * from gp_segment_configuration ;
registration_order | role | status | port | hostname | address | description
