/**
* Registers interest in the lease with the given name. Service instances should register their
* interest in leases as soon as they know about them; this gives the process an opportunity
* to notify the underlying cluster system that it is interested in the lease, or to setup
* other background tasks to acquire the lease if necessary. Note that registering interest
* in a lease doesn't necessarily mean that this service instance will attempt to acquire
* the lease; many clustering systems will only try to acquire leases for resources that
* they think they should own based on some consistent hashing system
