Monty Taylor bb8b4bf5a5 Swap human-facing links to use opendev.org

While we should not start using this for cloning things in the gate yet,
the opendev.org links provide for a nicer browsing experience already
even though the service is in beta. Go ahead and swap our browsing
links.

While in there, remove some masakari references to github links to the
source code. Masakari now publishes api docs to developer.openstack.org
so there is no need to point people to source code for api docs.

Managing Nodes

Node is a logical object managed by the Senlin service. A node can be a member of at most one cluster at any time. A node can be an orphan node which means it doesn't belong to any clusters.

List Nodes

To examine the list of Nodes:

../../examples/clustering/node.py

When listing nodes, you can specify the sorting option using the sort parameter and you can do pagination using the limit and marker parameters.

Full example: manage node

Create Node

When creating a node, you will provide a dictionary with keys and values according to the node type referenced.

../../examples/clustering/node.py

Optionally, you can specify a metadata keyword argument that contains some key-value pairs to be associated with the node.

Full example: manage node

Get Node

To get a node based on its name or ID:

../../examples/clustering/node.py

Full example: manage node

Find Node

To find a node based on its name or ID:

../../examples/clustering/node.py

Full example: manage node

Update Node

After a node is created, most of its properties are immutable. Still, you can update a node's name and/or params.

../../examples/clustering/node.py

Full example: manage node

Delete Node

A node can be deleted after creation, provided that it is not referenced by any active clusters. If you attempt to delete a node that is still in use, you will get an error message.

../../examples/clustering/node.py

Full example: manage node

Check Node

If the underlying physical resource is not healthy, the node will be set to ERROR status.

../../examples/clustering/node.py

Full example: manage node

Recover Node

To restore a specified node.
