Steve Baker a6ff771ab7 Log all resource events during overcloud deploy 
This change switches the overcloud deploy stack polling with event
list polling. This uses the same technique as the recently added
heat stack-create --poll mode: Ib7d35b66521f0ccca8544fd18fb70e04eaf98e5a

There is a (CREATE|UPDATE)_(COMPLETE|FAILED) event generated when the stack
operation is complete, so this is used to decide when to stop polling.

Also, every time there is an event it is printed to the screen in log
style. This would give the user an indication that something is
happening, which is better than staring at nothing for minutes (hours).

On stack update, the oldest event from the previous operation is discovered and
that is used for the marker so that only new events are logged.

tripleoclient

OpenStackClient reference plugin module

The OSC plugin system is designed so that the plugin need only be properly installed for OSC to find and use it. It utilizes the setuptools entry points mechanism to advertise to OSC the plugin module and supported commands.

tripleoclient is an OpenStackClient (OSC) plugin implementation that implements commands useful for TripleO and the install and management of both an undercloud and an overcloud.

Discovery

OSC discovers extensions by enumerating the entry points found under openstack.cli.extension and initializing the given client module.

[entry_points]
openstack.cli.extension =
    oscplugin = oscplugin.plugin

The client module must implement the following interface functions:

  • API_NAME - A string containing the plugin API name; this is the name of the entry point declaring the plugin client module (oscplugin = ... in the example above) and the group name for the plugin commands (openstack.oscplugin.v1 = in the example below)
  • API_VERSION_OPTION (optional) - If set, the name of the API version attribute; this must be a valid Python identifier and match the destination set in build_option_parser().
  • API_VERSIONS - A dict mapping a version string to the client class
  • build_option_parser(parser) - Hook to add global options to the parser
  • make_client(instance) - Hook to create the client object

OSC enumerates the loaded plugins and loads commands from the entry points defined for the API version:

openstack.oscplugin.v1 =
    plugin_list = oscplugin.v1.plugin:ListPlugin
    plugin_show = oscplugin.v1.plugin:ShowPlugin

Note that OSC defines the group name as openstack.<api-name>.v<version> so the version should not contain the leading 'v' character.

This second step is identical to that performed for all but the Identity client in OSC itself. Identity is special due to the authentication requirements. This limits the ability to add additional auth modules to OSC.

Client

The current implementation of the tripleoclient Client class is an empty placeholder. This client object is not equired but OSC's ClientManager will maintain it as required and is the interface point for other plugins to access anything implemented by this plugin.
