config: convert _osd_memory_target to int

ceph.conf doesn't accept float value.

Typical error seen:
```
$ sudo ceph daemon osd.2 config get osd_memory_target
Can't get admin socket path: unable to get conf option admin_socket for osd.2:
parse error setting 'osd_memory_target' to '7823740108,8' (strict_si_cast:
unit prefix not recognized)
```

This commit ensures the value inserted in ceph.conf will be an integer.
