(2) it has been too long since the last known entry; or
(3) the node hostname, IP address, port, wallet, sw version, or disk capacity
has changed.

type UploadSelectionCache struct {
	// contains filtered or unexported fields
}

UploadSelectionCache keeps a list of all the storage nodes that are qualified to store data We organize the nodes by if they are reputable or a new node on the network. The cache will sync with the nodes table in the database and get refreshed once the staleness time has past.
