Lucas Alvares Gomes e651d9ef88 [OVN] Use OVN from packages
This patch changes the OVN module from DevStack to allow for using the
OSapackaged version of OVN instead of compiling it from source.

A new variable called OVN_BUILD_FROM_SOURCE has been introduced and when
set to False (the default value) OVN will then use the packaged version
for setting up DevStack.

Note, in the stop_ovn() function, the OVN metadata agent service name
was wrong and the service wasn't being stopped as part of ./unstack.sh.
This patch also fixed it as well.

Neutron plugin specific files

Neutron plugins require plugin specific behavior. The files under the directory, lib/neutron_plugins/, will be used when their service is enabled. Each plugin has lib/neutron_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/neutron-legacy calls the following functions when the $Q_PLUGIN is enabled

  • neutron_plugin_create_nova_conf : optionally set options in nova_conf
  • neutron_plugin_install_agent_packages : install packages that is specific to plugin agent e.g. install_package bridge-utils
  • neutron_plugin_configure_common : set plugin-specific variables, Q_PLUGIN_CONF_PATH, Q_PLUGIN_CONF_FILENAME, Q_PLUGIN_CLASS
  • neutron_plugin_configure_dhcp_agent
  • neutron_plugin_configure_l3_agent
  • neutron_plugin_configure_plugin_agent
  • neutron_plugin_configure_service
  • neutron_plugin_setup_interface_driver
  • has_neutron_plugin_security_group: return 0 if the plugin support neutron security group otherwise return 1
  • neutron_plugin_check_adv_test_requirements: return 0 if requirements are satisfied otherwise return 1
