Isaku Yamahata 0dd34df455 lib/quantum: refactor quantum plugins and third party 
As quantum plugin support is coming like floodlight, nvp and nec,
it's worth while to refactor quantum plugin logic so that each plugin can
be modified/enhanced intervening with other quantum plugin.
And new plugin support can be added easily (hopefully) without modifying
core logic.

Quantum plugin specific files

Quantum plugins require plugin specific behavior. The files under the directory, lib/quantum_plugins/, will be used when their service is enabled. Each plugin has lib/quantum_plugins/$Q_PLUGIN and define the following functions. Plugin specific configuration variables should be in this file.

  • filename: $Q_PLUGIN
    • The corresponding file name MUST be the same to plugin name $Q_PLUGIN. Plugin specific configuration variables should be in this file.

functions

lib/quantum calls the following functions when the $Q_PLUGIN is enabled

  • quantum_plugin_create_nova_conf : set NOVA_VIF_DRIVER and optionally set options in nova_conf e.g. NOVA_VIF_DRIVER=${NOVA_VIF_DRIVER:-"nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver"}
  • quantum_plugin_install_agent_packages : install packages that is specific to plugin agent e.g. install_package bridge-utils
  • quantum_plugin_configure_common : set plugin-specific variables, Q_PLUGIN_CONF_PATH, Q_PLUGIN_CONF_FILENAME, Q_DB_NAME, Q_PLUGIN_CLASS
  • quantum_plugin_configure_debug_command
  • quantum_plugin_configure_dhcp_agent
  • quantum_plugin_configure_l3_agent
  • quantum_plugin_configure_plugin_agent
  • quantum_plugin_configure_service
  • quantum_plugin_setup_interface_driver
