This adds support for configuring some key parameter using environment variables. This is useful, and recommended (cf. twelve-factor app), when running in a environment where changing the configuration file across deployments (e.g. k8s in our case). At the moment, only a subset of configuration parameters are supported. It's currently quite a hack and should probably be merged with the existing configuration mechanism, which currently supports file and cli arguments.

This module provides two k8s specific actors * `K8sMdtModifierActor`, which add k8s metadata to reports and forward them to another actor. * `K8sMonitorAgent`, which monitors the k8s API and sends messages when pod are created, removed or modified. Signed-off-by: Pierre Rust <pierre.rust@orange.com>
This exporter exposes one gauge and one counter metric * for rapl energy (total cpu energy usage) * for the global energy usage estimated by powerAPI * for the estimated energy usage of each pod (filtered by labels) Signed-off-by: Pierre Rust <pierre.rust@orange.com>
Adds configuration and launches the modifier agent for K8S metadata. Signed-off-by: Pierre Rust <pierre.rust@orange.com>

This adds support for Kubernetes to smartwatts.
Main features
This PR should be used as a basis for discussion, some code should most probably be moved to the PowerAPI repository and more care should be payed to make sure we don't cause any issue when running smartwatts outside k8s.
