After discussion:
The problem is that `addShard` and `--configdb` are supposed to have the
same values, matching textually. Can't have hostname at one place, IP at the
other. Atm `--configdb` uses
`getAttribute(MongoDBConfigServer.SUBNET_HOSTNAME)`, while `addShard` uses the
public `MONGO_SERVER_ENDPOINT` initialized with
`BrooklynAccessUtils.getBrooklynAccessibleAddress`. The solution would be to
use `addShard` with `SUBNET_HOSTNAME` as well. Shouldn't matter for cloud
machines (where the values match), but for localhost they are different.
Optional improvements:
* update documentation of `MONGO_SERVER_ENDPOINT` and
`HTTP_INTERFACE_URL` to indicate that they are public IPs (better not be used
for local connections)
* Implement `HasSubnetHostname` for
`LocalhostMachineProvisioningLocation` returning `localhost`, so that
`Machines.getSubnetHostname` doesn't return `127.0.0.1` (for consistence).
