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: {} Change-Id: Ie0c00fdb58373206071daa1fb13faf175c4313e0 Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
