[linux-lvm] discuss: about master branch vgcreate parameter "--clustered"

[heming.zhao at suse.com]

Hello,

On master branch, clvmd had been removed, the "-c | --clustered" is deprecated.

```
~> sudo vgcreate -c n vg1 /dev/sda
The clustered option is deprecated, see --shared.
Run `vgcreate --help' for more information.
~> echo $?
3
```

It looks the -c is useless, it only shows deprecated info and exit.
Is it possible to remove the -c from lvm code?

Thanks & Merry Christmas
