Initially, this patch ensured that the custom configuration and readiness checks were applied after every restart of the OVN North services. However, after removing the call that triggered the restarting of the OVN/OVS services in [1], this patch now serves as a refactor, separating the readiness checks and custom configuration into a dedicated function.

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.
- The corresponding file name MUST be the same to plugin name
functions
lib/neutron calls the following functions when the $Q_PLUGIN is enabled
neutron_plugin_create_nova_conf: optionally set options in nova_confneutron_plugin_install_agent_packages: install packages that is specific to plugin agent e.g. install_package bridge-utilsneutron_plugin_configure_common: set plugin-specific variables,Q_PLUGIN_CONF_PATH,Q_PLUGIN_CONF_FILENAME,Q_PLUGIN_CLASSneutron_plugin_configure_dhcp_agentneutron_plugin_configure_l3_agentneutron_plugin_configure_plugin_agentneutron_plugin_configure_serviceneutron_plugin_setup_interface_driverhas_neutron_plugin_security_group: return 0 if the plugin support neutron security group otherwise return 1neutron_plugin_check_adv_test_requirements: return 0 if requirements are satisfied otherwise return 1
