Enhancement Request: please do not reboot both nodes simultaneously when applying core config keys

Hi,

I have an enhancement request of the logic for applying core config keys,
because applying core config keys brings with rebooting both nodes almost simultaneously -- we cannot accept this downtime.

To prevent downtime when applying keys, could you modify the logic that users can take control when a node reboot occurs?

One suggestion of the logic is this:
- Add below 2 lines on '/opt/oracle/oak/lib/oaklib/apply' file before line 213.
    print "Are you ready? Please press any key to continue.";
    my $confirmation = <STDIN>;
  (FYI: contents after line 213 is below)
    213   # apply the license
    214   msgPrint(*STDOUT,"I", "license", "Applying core_config_key on '$node_list[$node_num]'");
