History
Phil Sphicas 292e94ee2c Avoid expensive MAAS API calls 
The MAAS API call "GET /MAAS/api/2.0/machines/" retrieves information
about every machine known to MAAS, which is very slow. The API supports
filtering based on hostname and mac_address (among others), and querying
for power parameters for all nodes at once.

This change modifies identify_baremetal_node to avoid calling refresh on
the full machine list.

Also, the refresh method of ResourceCollectionBase is updated to allow
passing of params, which can be used to take advantage of the filtering.
Note that a filtered call to refresh overwrites the resources collection
to only contain the returned values.

Most calls to Machines.refresh() aren't really needed at all - they are
replaced with a call to Machines.empty_refresh(), which will still make
sure that the API endpoint is accessible but return an empty collection.
(This may get removed entirely in the future.)

MaaS Node Driver

This driver will handle node provisioning using Ubuntu MaaS 2.1. It expects the Drydock config to hold a valid MaaS API URL (e.g. http://host:port/MAAS/api/2.0) and a valid API key for authentication.

Drydock Model to MaaS Model Relationship

Site

Will provide some attributes used for configuring MaaS site-wide such as tag definitions and repositories.

Network Link

Will provide attributes for configuring Node/Machine interfaces

Network

MaaS will be configured with a single 'space'. Each Network in Drydock will translate to a unique MaaS fabric+vlan+subnet. Any network with an address range of type 'dhcp' will cause DHCP to be enabled in MaaS for that network.

Hardware Profile

A foundation to a Baremetal Node definition. Not directly used in MaaS

Host Profile

A foundation to a Baremetal Node definition. Not directly used in MaaS

Baremetal Node

Defines all the attributes required to commission and deploy nodes via MaaS

  • bootdisk fields and partitions list - Define local node storage configuration to be implemented by MaaS
  • addressing and interface list - Combined with referenced network links and networks, define interface (physical and virtual (bond / vlan)) configurations and network addressing
  • tags and owner data - Statically defined metadata that will propagate to MaaS
  • base_os - Select which stream a node will be deployed with
  • kernel and kernel params - Allow for custom kernel selection and parameter definition
