Add the capability to set remote property values via a RemoteProperty

[mikebaum]

Currently the RemoteProperty class offers no "setter". This issue tracks the work to add mechanisms to set remote property values. My initial thoughts are to add at least five methods:

    public void setValue(T value); // blocking

    public  CompletableFuture<Void> setValueAsync(T value); // non-blocking

    public boolean isLocked(); // checks if the remote property is locked

    public void lock(); // blocks until lock acquired without timeout

    public void unlock(); // unlock

There may eventually be a need to add methods like, compareAndSet(expected, newValue) or tryLock() (with or without timeout) and/or lock(timeout)
