Dougal Matthews b2ad22819b Remove Tuskar from the CLI usage 
The command line workflows with Tuskar have proven to be more limited than
using Heat directly. This change removes Tuskar from the CLI documentation and
updates all the examples.

Essentially this means removing all uses of --plan in the deploy command and
all other 'openstack management ...' commands.

Tuskar is still referenced in a number of places and can't be fully removed
until there is an alternative for the Tuskar UI.

Deleting Overcloud Nodes

You can delete specific nodes from an overcloud with command:

openstack overcloud node delete --stack $STACK_NAME --templates [templates dir] <list of nova instance IDs>

This command updates the heat stack with updated numbers and list of resource IDs (which represent nodes) to be deleted.

Note

If you passed any extra environment files when you created the overcloud (for instance, in order to configure network isolation <../advanced_deployment/network_isolation>), you must pass them again here using the -e or --environment-file option to avoid making undesired changes to the overcloud.

Note

Before deleting a compute node please make sure that the node is quiesced, see quiesce_compute.

Note

A list of nova instance IDs can be listed with command:

nova list
