Currently, the expiration of every element in a set or map
is a read-only parameter generated at kernel side.
This change will permit to set a certain expiration date
per element that will be required, for example, during
stateful replication among several nodes.
This patch allows to propagate NFTA_SET_ELEM_EXPIRATION
from userspace to the kernel in order to set the
configured value.
