Add missing template functionality to lifecycle_node. (#707)

* Add missing template functionality to lifecycle_node.

Recent changes to the node_parameters interface was accompanied by additions to the
node.hpp header and implementation files. However, these additions were not also made
to the corresponding lifecycle node files. This PR includes the changes required for
the lifecycle node.

Going forward, I suggest that any code like this that supplements the basic node interfaces
should either be factored out into a separate header that both node and lifecycle_node
include, or that the supplemental code simply be included in the appropriate node_interface
file directly, if possible. That way we can avoid code duplication and its symptoms which
is node and lifecycle_node getting out of sync (which they have several times).
