[$] SIGnals from KubeCon

The basic organizational construct within the Kubernetes project is a setof Special Interest Groups (SIGs), each of which represents a different area ofresponsibility within the project. Introductions to what the various SIGsdo, as well as more detailed sessions, were a core part of KubeCon + CloudNativeCon Europe 2019, as the different groups explained whatthey're doing now and their plans for the future. Two sessions, inparticular, covered the work of the Release and Architecture SIGs, both ofwhich have a key role in driving the project forward.
