The muted group index was using a `absl::flat_has_set` the use of flat data structure lead to oversized allocation when the number of muted/skipped raft group was large. Replaced a hash set with roaring bitmap. The roaring bitmap is efficient and compressed leading to better performance and smaller allocation. Fixes: redpanda-data#12005 Signed-off-by: Michal Maslanka <[email protected]> (cherry picked from commit 745c324)
