/**
* Factory for {@link RemoteCache}s.
* In order to be able to use a {@link RemoteCache}, the
* {@link RemoteCacheManager} must be started first: this instantiates connections to Hot Rod server(s). Starting the
* {@link RemoteCacheManager} can be done either at creation by passing start==true to the constructor or by using a
* constructor that does that for you; or after construction by calling {@link #start()}.
* NOTE: this is an "expensive" object, as it manages a set of persistent TCP connections to the Hot Rod
* servers. It is recommended to only have one instance of this per JVM, and to cache it between calls to the server
* (i.e. remoteCache operations)
* {@link #stop()} needs to be called explicitly in order to release all the resources (e.g. threads,
* TCP connections).
