add collectd resource node capability

allow manually adding collectd nodes using Node context.

if a node is present with a collectd config dict then
we can create a ResourceProfile object for it
and connect to collectd.

example

nodes:
-
    name: compute_0
    role: Compute
    ip: 1.1.1.1
    user: root
    password: r00t
    collectd:
        interval: 5
        plugins:
            ovs_stats: {}
