Fix recent daily CI test failures (#9966)

Recent PRs have introduced some failures, this commit
try to fix these CI failures. Here are the changes:

1. Enable debug-command in sentinel test.
```
Master reboot in very short time: ERR DEBUG command not allowed. If the
enable-debug-command option is set to "local", you can run it from a
local connection, otherwise you need to set this option in the
configuration file, and then restart the server.
```

2. Enable protected-config in sentinel test.
```
SDOWN is triggered by misconfigured instance replying with errors: ERR
CONFIG SET failed (possibly related to argument 'dir') - can't set
protected config
```

3. Enable debug-command in cluster test.
```
Verify slaves consistency: ERR DEBUG command not allowed. If the
enable-debug-command option is set to "local", you can run it from a
local connection, otherwise you need to set this option in the
configuration file, and then restart the server.
```

4. quicklist fill should be signed int.
The reason for the modification is to eliminate the warning.
Modify `int fill: QL_FILL_BITS` to `signed int fill: QL_FILL_BITS`

The first three were introduced at #9920 (same issue).
And the last one was introduced at #9962.
