Update configuration group

Comma-separated fields to update: name, description, tags, priorityOrder, family.description, family.active, family.raw, family.preset, or one field inside family.raw or family.preset, such as family.raw.metadata or family.preset.chartVersion. family.raw and family.preset replace the whole family content; a field inside them changes only that field and keeps the others. A listed field that is omitted from the body is cleared (description, tags, family.description, and optional fields inside family.raw or family.preset) or reset to its default (priorityOrder 0, family.active false). name cannot be cleared, and family.raw.remoteConfigurations cannot be empty. Changing family.preset.chartVersion without family.preset.integrationVersion uses the default integration version of the new chart version. The body must include the arm being changed, and only the arm matching the current family's content type is accepted (raw and preset families cannot be switched). A bare family, unknown paths, and * return 400.
