> Alerts for services that support a standard HA mode (nameservice and/or alias) need to
be able to understand how to calculate the correct server to contact. This means building
a dynamic key to use when discovering the URL to use for METRIC and WEB alerts.
> The proposal is to add a new child element to the URL parameter:
> {code}
> "high_availability": {
>   "nameservice": "{{hdfs-site/dfs.nameservices}}",
>   "alias_key" : "{{hdfs-site/dfs.ha.namenodes.{{ha-nameservice}}}}",
>   "http_pattern" : "{{hdfs-site/dfs.namenode.http-address.{{ha-nameservice}}.{{alias}}}}",
>   "https_pattern" : "{{hdfs-site/dfs.namenode.https-address.{{ha-nameservice}}.{{alias}}}}"
> {code}
