lvcreate: add --activate ay (autoactivate)

One can use "lvcreate --aay" to have the newly created volume
activated or not activated based on the activation/auto_activation_volume_list
this way.

Note: -Z/--zero is not compatible with -aay, zeroing is not used in this case!
When using lvcreate -aay, a default warning message is also issued that zeroing
is not done.
