This change allows for messages to be signed when message signing is enabled and a system
key is not present. This is accomplished by generating a random key on startup and then using
HKDF with HmacSHA1 to generate the keying material to be used to sign the messages. The random
key from the originating node is added to the signed message so that the signing key can be
derived on the receiving node.
When a system key is present, the system key is used for signing and the preexisting behavior
is maintained.

Original commit: elastic/x-pack-elasticsearch@c41fdc0ac3
This adds the release notes to the documentation for Shield. Note, two new features do not
have links as the documentation for these are still pending.
Original commit: elastic/x-pack-elasticsearch@e66df5cf14
This commit changes the groupId to the above mentioned one
so that S3 uploads will end up in the right bucket. This will
allow the Elasticsearch plugin manager to install the commercial
plugins like
```
bin/plugin install {watcher,shield,license,marvel}
```
like the official ones.
