   ### Is your feature request related to a problem or challenge?
   
   From `ParquetExec` metrics, with predicate pushdown enabled:
   
   > metrics=[output_rows=0, elapsed_compute=96ns, 
row_groups_matched_bloom_filter=0, row_groups_matched_statistics=21050, 
file_scan_errors=0, pushdown_rows_matched=0, 
row_groups_pruned_statistics=173576, row_groups_pruned_bloom_filter=21050, 
file_open_errors=0, num_predicate_creation_errors=0, bytes_scanned=25023432248, 
pushdown_rows_pruned=0, page_index_rows_pruned=0, 
predicate_evaluation_errors=0, page_index_rows_matched=0, 
time_elapsed_scanning_until_data=16.622753ms, 
time_elapsed_processing=72.280463608s, pushdown_eval_time=382ns, 
page_index_eval_time=3.177676ms, time_elapsed_scanning_total=16.661811ms, 
time_elapsed_opening=102.989073638s]
   
   For example, `pushdown_rows_matched` and `pushdown_rows_pruned` are far away 
from each other, even though they refer to roughly the same thing.
   
   The unstable sort also makes it hard to compare multiple `EXPLAIN ANALYZE` 
results.
   
   ### Describe the solution you'd like
   
   Sort them alphabetically, to break ties in the (very) partial order induced 
by `MetricValue::display_sort_key`
   
   ### Describe alternatives you've considered
   
   Split `Metrics` by categories and display each on a line; or split 
`ParquetExec` into "virtual" execution plans to reflect the successive opening 
and filtering steps done in `ParquetOpener`. That is more work, though.
