Feature Request: Use block storage with sst.aws.Service

[shreyassanthu77]

It'd be very nice if we could use block storage with the sst aws ecs service. This would be very helpful to host dbs and stuff. The api would probably look something like

// other config
const efs = new sst.aws.Storage("Block", { ... });
// ...
cluster.addService({
    // other service config
    mountPoints: [
        { path: "/data", volume: efs }
    ]
});

this should also probably have options for transitEncryption and stuff
