RFR: 7116990: (spec) Socket.connect(addr,timeout) not clear if IOException because of TCP timeout [v4]

[Jaikiran Pai]

> Can I please get a review of this doc-only change which proposes to add a `@apiNote` to the `Socket.connect(SocketAddress endpoint, int timeout)` method? This addresses https://bugs.openjdk.org/browse/JDK-7116990.
> 
> As noted in that issue, users can find it surprising that when the `Socket.connect(...)` method is called with a `timeout` value, then if that timeout value happens to be greater than the connect timeout that operating systems typically impose, then a `IOException` gets thrown instead of the `SocketTimeoutException`. The change in this PR proposes to add a `@apiNote` which explains this current behaviour.
> 
> If this requires a CSR, I'll open one once we settle on the proposed text.

 - Mark's suggestion - use "connect timeout" instead of "connection timeout"
 - Daniel's suggestion for the text
