Adds OnSubnetNetworkEnricher
Some entities publish their endpoint using the public hostname (e.g.
`MySqlNode` publishes `datastore.url` using the sensor `host.name`). If trying
to connect to it from within the same subnet, this can fail if the public
ip/hostname is not accessible.
This topic is covered in the "Working with Multiple Networks" proposal (see
dev@brooklyn email thread). That suggests we should use the subnet address in
things like the datastore.url. That will likely break things for some of our
users. But while we discuss/finalise that proposal...
This enricher allows one to publish another sensor that definitely uses the
subnet address. It will publish the sensor as things like
`datastore.url.mapping.subnet`.
This is really a temporary solution (hence marking this as `@Beta`).
