// Reserve is invoked to acquire a key and set it to a given value. Value can only be a string or []byte since
// the etcd API accepts only a string. Timeout defines how long the function will wait for a response. TTL
// defines how long that reservation is valid. When TTL expires the key is unreserved by the KV store itself.
