Delete a consumer role

Deletes the role. A role that consumers, applications or API proxy authorization settings still hold is 409 dependencyConflict (reason roleInUse; params consumerCount, applicationCount, apiProxyCount) and nothing changes. With force=true the role is deleted the way the Consumer Roles screen deletes it: removed from those consumers, applications and API proxies, then undeployed. runtimeDeployment reports the gateway undeploy.
