    Sent a resource provider message when providers subscribe.

    In order to inform users of resource provider managers that the
    managed resources have changed, we add a new 'ResourceProviderMessage'
    type for communicating changes to the managed total resources.

    We add code to trigger sending of that message when a resource
    provider subscribes with the manager.

    In the future this message could also be used to communicate changes
    to an already subscribed resource provider's total resources.

> When a resource provider registers with a resource provider manager, the manager should sent a message to its subscribers informing them on the changed resources.
> For the first iteration where we add agent-specific, local resource providers, the agent would be subscribed to the manager. It should be changed to handle such a resource update by informing the master about its changed resources. In order to support master failovers, we should make sure to similarly inform the master on agent reregistration.
