[pve-devel] applied: [PATCH manager] fix #4808: ceph: use setting names with underscores

[Maximiliano Sandoval]

> Also, did you checked for other such occurrences in our API?

I found another place where they are used in pve-manager's PVE/API2/Ceph module.
I will send a patch, but most interesting is that we set

     $cfg->{global}->{'osd pg bits'} = $param->{pg_bits};
     $cfg->{global}->{'osd pgp bits'} = $param->{pg_bits};

and expose them in the API. This setting is documented in the Pacific docs [1],
but not in the Quincy docs [2]. I could not find much info about this. It is not
mentioned on the Quincy release notes [3] as far as I can tell.
