> Adds "host-only" alerts to the alert framework infrastructure. Alerts that are only for a host are those that are run on every host in the cluster and are not bound to any particular stack service. They exist "outside" of the stack.
> In order to accomplish this, several changes were made:
> 1) A new alerts.json was created at the root resources directory to represent host-only alerts. This file is parsed separately from the stack but its definitions are merged into the database in the same manner as those from the stack
> 2) These new alerts must be bound to the service AMBARI and component AMBARI_AGENT
> 3) Host alerts are usually custom scripts; a new directory was needed so that resources could be copied from the Ambari Server to the Agent in the same manner that the stack and custom_actions resources are copied. This is the new "host_scripts" directory.
> 4) RPM updates to ensure that "host_scripts" is properly packaged.
