This annotation is used to indicate which distribution contexts that a ServiceMonitor is useful for.
The current distribution contexts are defined in the enum type DistributionContext.
If a ServiceMonitor is unannotated then it will be assumed that the ServiceMonitor is only valid when
run in the OpenNMS deamon context.
If the annotation exists but no contexts are specified then it is assumed that it works in all contexts.
Reasons that a monitor may not work in all contexts would be for example because it accesses location config
files or uses local daemon services.
Note that this annotation does not inherit.
