Explore adding support for Datadog Integrations

[martinrusev]

Datadog recently separated their individual checks into separate packages, which will work great with the amonagent:

Based on the license we can use them on any machine. That seems nice.

Will it be as simple as using other checks/metrics?

@dschwabeS11 Based on what I saw in their source code, it is going to be very similar to how Nagios/Sensu plugins work - you add the path to the datadog script in a JSON list
