Create an 'LMA-Infra' Composite

This composite deploys the logging and prometheus operators
such that they are ready to collect logs and metrics from a k8s cluster.
The operators can be extended by introducing custom resources, allowing
any application running in the cluster to use these services

Note: Due to [0], this composite cannot be successfully deployed in the
initinfra-target phase, so a separate 'lma-infra' phase is introduced

+# LMA Infra
+
+This composite deploys the logging-operator and kube-prometheus-stack,
+configured to provide basic LMA facilities to a cluster. Application Logs and
+metrics can be collected by supplying the operators CRs.
