Simplify how workload-team-defs reacts to a workload-teams-repo configmap change

What does this MR do and why?

This MR is replacing the reconcile-workload-team-defs-helmrelease Kyverno Policy with a native Flux mechanism introduced in 2.8 (see https://fluxcd.io/flux/components/helm/helmreleases/#reacting-immediately-to-configuration-dependencies). The workload-team-defs ConfigMap, is now labeled reconcile.fluxcd.io/watch: Enabled, so helm-controller upgrades the release as soon as the aggregate-team-defs policy updates it.

Closes #4619 (closed)

Test coverage

Tested on my dev cluster on a dummy HelmRelease pointing to a ConfigMap containing the label. On a ConfigMap change, a Helm upgrade was triggered after ~5 seconds.

Global config for deployment pipelines

• autorun pipelines
• allow failure on pipelines
• record sylvactl events

Notes:

• Enabling autorun will make deployment pipelines to be run automatically without human interaction
• Disabling allow failure will make deployment pipelines mandatory for pipeline success.
• if both autorun and allow failure are disabled, deployment pipelines will need manual triggering but will be blocking the pipeline

Be aware: after configuration change, pipeline is not triggered automatically. Please run it manually (by clicking the run pipeline button in Pipelines tab) or push new code.
