Add variable to define a beat service state

This patch aims to provide the user a way to enable/disable
beats by overriding {beatname}_service_state variable accordingly
to the beats that the users wants to be receiving data.

There are some use cases that users just wants a subset of the
beats provided, mostly to avoid unecessary use of bandwidth
with data that woudn't be used. So the way that this patch proposes
this use case is just enable/disable after install, keeping the service
installed in case of the users needs it.
