commit c56a372e066c0c088c2aa86e984ba13a8f821d1a

[improvement][fix](grouping-set)(tablet-repair) optimize compaction too
slow replica process, (#8123)
1. optimize compaction too slow replica process, will set to ok if the
replica compaction is done.
And will not set bad if more than half replica is too slow,
2. fix field in grouping_id() is not the same name will cause error lile
`select list expression not produced by
aggregation output (missing from GROUP BY clause?): id`
