Decided to take a short break from the work on QUIC
to implement a DTLS API. Very experimental at this
point but the basic API is there (inspired by the
QUIC API work).
The implementation is based on OpenSSL's built-in
DTLS support and no other dependencies are required.
DTLS is a datagram-based version of TLS that is used
for things like WebRTC and CoAP. It provides similar
security guarantees as TLS but is designed to work over
UDP instead of TCP.
This shouldn't be considered ready for production
but it is a good starting point for experimentation
and feedback.
```bash
./configure --experimental-dtls
make -j{nproc}
./node --experimental-dtls my-dtls-app.js
```

RSLGTM, the API makes sense.
Before enabling in the default build, make sure to have your agent do a pass in finding security bugs, as I don't want us to be spammed.

@nodejs ... per our new "large PR" rules. this needs an additional @nodejs/tsc sign off before it can land. |

I might have overlooked it, but I didn't see a test for expectsWarning from experimental usage. There's a warning, but no assertion to it (non-blocking tho)
