e34507c739 feat(stats): add host_netinfo networking information stats family
Introduce host_netinfo stats family to hold information regarding host
networking. At the moment, it only provides ipv4 and ipv6 addresses
list for each interface available on the host. The naming schema for
the introduced stats is
falco.host_netinfo.interfaces.<ifname>.protocols.<ipv4|ipv6>.addresses.

a1ff7c7384 fix(falco_metrics): remove ifinfo_json stat/metric
Using JSON as value prevents any meaningful aggregation for the stats.
Splitting these information into multiple labels can drastically
increase the number of dimensions, as the number of interfaces and
addresses can be high in some environment. Moreover, these information
are not currently refreshed, even if they can frequently change. Given
these reasons, remove ifinfo_json from stats and metrics.

## The Falco Project
## Falco Repo: Powering the Core of The Falco Project
The Falco Project codebase is maintained under the [falcosecurity GitHub organization](https://github.com/falcosecurity). The primary repository, [falcosecurity/falco](https://github.com/falcosecurity/falco), holds the source code for the Falco binary, while other sub-projects are hosted in dedicated repositories. This approach of isolating components into specialized repositories enhances modularity and focused development. Notable [core repositories](https://github.com/falcosecurity/evolution?tab=readme-ov-file#core) include:
This is the main Falco repository which contains the source code for building the Falco binary. By utilizing its [libs](https://github.com/falcosecurity/libs) and the [falco.yaml](falco.yaml) configuration file, this repository forms the foundation of Falco's functionality. The Falco repository is closely interconnected with the following *core* repositories:
- [falcosecurity/libs](https://github.com/falcosecurity/libs): This repository hosts Falco's core libraries, which constitute the majority of the binarys source code and provide essential features, such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): It contains the official ruleset for Falco, offering pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins): This repository supports integration with external services through plugins that extend Falco's capabilities beyond syscalls and container events, with plans for evolving specialized functionalities in future releases.
- [falcosecurity/falcoctl](https://github.com/falcosecurity/falcoctl): A command-line utility designed for managing and interacting with Falco.
- [falcosecurity/charts](https://github.com/falcosecurity/charts): This repository provides Helm charts for deploying Falco and its ecosystem, simplifying the installation and management process.
- [falcosecurity/libs](https://github.com/falcosecurity/libs): Falco's libraries are key to its fundamental operations, making up the greater portion of the source code of the Falco binary and providing essential features such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): Contains the official ruleset for Falco, providing pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins/): Falco plugins facilitate integration with external services, expand Falco's capabilities beyond syscalls and container events, and are designed to evolve with specialized functionality in future releases.

## Getting Started with Falco
If you're new to Falco, begin your journey with our [Getting Started](https://falco.org/docs/getting-started/) guide. For production deployments, please refer to our comprehensive [Setup](https://falco.org/docs/setup/) documentation.
Carefully review and follow the [Official Documentation](https://falco.org/docs/install-operate/).
As final recommendations before deploying Falco, verify environment compatibility, define your detection goals, optimize performance, choose the appropriate build, and plan for SIEM or data lake integration to ensure effective incident response.
Considerations and guidance for Falco adopters:
1. Understand dependencies: Assess the environment where you'll run Falco and consider kernel versions and architectures.
2. Define threat detection objectives: Clearly identify the threats you want to detect and evaluate Falco's strengths and limitations.
3. Consider performance and cost: Assess compute performance overhead and align with system administrators or SREs. Budget accordingly.
4. Choose build and customization approach: Decide between the open source Falco build or creating a custom build pipeline. Customize the build and deployment process as necessary, including incorporating unique tests or approaches, to ensure a resilient deployment with fast deployment cycles.
5. Integrate with output destinations: Integrate Falco with SIEM, data lake systems, or other preferred output destinations to establish a robust foundation for comprehensive data analysis and enable effective incident response workflows.
### Demo Environment
A demo environment is provided via a docker-compose file that can be started on a docker host which includes falco, falcosidekick, falcosidekick-ui and its required redis database. For more information see the [docker-compose section](docker/docker-compose/)

**Example 1** Let's consider a feature _foo_ in the Output/Alerts Area introduced in Falco 1.0.0 and labeled as *Incubating*. The feature is promoted to *Stable* in Falco 1.1.0 (because the feature did not get any user-facing change).
Subsequently, maintainers decide that backward-incompatible changes must be introduced in _foo_ to improve its functionality. The part of the feature to be changed is labeled as *Deprecated* in Falco 1.2.0, and the deprecation period starts. The non-backward compatible change is then introduced in Falco 1.4.0.

**Example 2** The `--bar` flag in the CLI/Config Area has been introduced since Falco 1.1.0 and is labeled as *Stable*. Before releasing Falco 1.5.0, maintainers realize `--bar` is redundant and should be removed. The flag is labeled as *Deprecated* in Falco 1.5.0, and the deprecation period starts. The flag is removed in Falco 1.6.0.
