Add support for Ubuntu 24.04 LTS (Noble) to the charm while maintaining backward compatibility with Ubuntu 22.04 (Jammy). Summary of changes: * Add Noble base configuration to charmcraft.yaml with multi-architecture support (amd64, s390x, ppc64el, arm64) * Add 'noble' series to metadata.yaml * Update osci.yaml CI configuration: - Add charm-unit-jobs-py312 template for Python 3.12 - Add openstack-loadbalancer-noble job definition - Upgrade charmcraft channel from 2.0/stable to 3.x/stable * Add complete Noble test bundle configuration * Refactor overlay templates to use shared local_overlay.yaml.j2 to eliminate code duplication between Ubuntu versions This change enables the charm to run on both Ubuntu 22.04 and 24.04 systems, with Noble becoming the primary test target while maintaining Jammy compatibility for existing deployments.

Overview
The openstack-loadbalancer charm deploys a loadbalancer that can load balance traffic over a number of units of a service. The charm supports using vips accross the loadbalancer units to provide HA.
Usage
Configuration
This section covers common and/or important configuration options. See file
config.yaml for the full list of options, along with their descriptions and
default values. See the Juju documentation for details
on configuring applications.
vips
Sets the VIPs to use on the openstack-loadbalancer units to provide fault tolerant access to a servce. The value should be a space seperated list of IPs.
Deployment
The charm has public, admin and internal space bindings. These are the
spaces that the charm will create listeners on for ingress traffic. The charm
vips option should be used to provice an IP on each one of these network
spaces.
This charm needs to be related to the hacluster charm to manage vips and the haproxy service.
juju deploy -n 3 openstack-loadbalancer
juju config openstack-loadbalancer vip="10.0.0.100 10.10.0.100 10.20.0.100"
juju deploy hacluster openstack-loadbalancer-hacluster
juju relate openstack-loadbalancer:ha openstack-loadbalancer-hacluster:ha
To provide a load balancer relate the charm to a service that supports the loadbalancer interface.
