Initial release 
Send AlertManager notifications to Elasticsearch

Add a new service, `alertmanager2es`, which receives [HTTP webhook
notifications][] from [AlertManager][] and inserts them into an
[Elasticsearch][] index for searching and analysis.

Notifications are received on the `/webhook` endpoint.

Prometheus metrics are exposed on `/metrics`.

Note that this service will not capture silenced or inhibited alerts
currently.

I used a custom type for `groupKey` so that the `groupKey` field can be
marshalled into JSON as a string, since Elasticsearch does not currently
support unsigned integers:

https://github.com/elastic/elasticsearch/issues/13951

I tested extensively to try to map the integer to a string using
Elasticsearch's mappings, which I succeeded in doing, however Kibana
then failed to display the documents because Elasticsearch's
highlighting could not handle the unsigned integer stored in `_source`:
