More types of output for unfurl status

[detjensrobert]

Debugging types ordering would be easier with some improvements to the unfurl plan / unfurl status outputs:

a) plan should show the type in addition to the resource name
b) plan should show the known properties/attributes of the resource (when verbose)
c) plan should report what dependencies a node is waiting on

#    a):
Node unfurl.nodes.HttpsProxyContainerComputeHost "dockerhost" (pending):
# b):
- variables:
    protocol: https
    ports: [443]
    subdomain: foo
    public_dns: foo.domain.com
    # etc
- deploy:
    - operation create (reason: add)
       rendered at .../planned/tasks/dockerhost
       rendered at .../planned/secrets/dockerhost
    - operation configure (reason: add)
#    a):
Node unfurl.nodes.EC2Compute "nxcvm" (pending):
- deploy:
    - operation create (reason: add)
                                     # c):
       (render waiting for dependents: "dockerhost", "...")

• Some sort of graph output for dependencies in an ensemble would also be helpful for seeing all of the dependencies of an object.

Something like unfurl (plan|status) --graph that outputs Graphviz with the relationship names:

digraph G {
  rankdir = BT

  "aws_metadata" -> "dockerhost-aws-bootimage"
  "nxcvm" -> "aws_metadata"
  "nxcvm" -> "dockerhost"

  "__dns-zone" -> "nxcvm"
  "aws-ebs-volume" -> "nxcvm"

  "volume" -> "nxcvm"           [label=<<font color="red">.source</font>>]
  "volume" -> "aws-ebs-volume"  [label=<<font color="red">.target</font>>]
