8bcade7cfa Cluster Manager: compare key values after BUSYKEY error (migration). 
If a key exists in the target node during a migration (BUSYKEY),
the value of the key on both nodes (source and target) will be compared.
If the key has the same value on both keys, the migration will be
automatically retried with the REPLACE argument in order to override
the target's key.

If the key has different values, the behaviour will depend on such
cases:
- In case of 'fix' command, the migration will stop and the user
  will be warned to manually check the key(s).
- In other cases (ie. reshard), if the user launched the command
  with the --cluster-replace option, the migration will be
  retried with the REPLACE argument, elsewhere the migration will
  stop and the user will be warned.

eb86c4c282 evict: don't care about mem if loading 
When loading data, we call processEventsWhileBlocked
to process events and execute commands.
But if we are loading AOF it's dangerous, because
processCommand would call freeMemoryIfNeeded to evict,
and that will break data consistency, see issue #5686.

83b0df508c Reject EXEC containing write commands against RO replica. 
Thanks to @soloestoy for discovering this issue in #5667.
This is an alternative fix in order to avoid both cycling the clients
and also disconnecting clients just having valid read-only transactions
pending.

bad0b20979 fix #5580, display fragmentation and rss overhead bytes as signed 
these metrics become negative when RSS is smaller than the used_memory.
This can easily happen when the program allocated a lot of memory and haven't
written to it yet, in which case the kernel doesn't allocate any pages to the process
