The running flag is needed to discriminate starting and started HA resources from each other, which is needed to correctly account for HA resources for the dynamic load usage implementation in the next patch. This is because for the dynamic load usage, any HA resource, which is scheduled to start by the HA Manager in the same round, will not be accounted for in the next call to score_nodes_to_start_resource(...). This is not a problem for the static load usage, because there the current node usages are derived from the running resources on every call already. Passing only the HA resources' 'state' property is not enough since the HA Manager will move any HA resource from the 'request_start' (or through other transient states such as 'request_start_balance' and a successful 'migrate'/'relocate') into the 'started' state. This 'started' state is then picked up by the HA resource's LRM, which will actually start the HA resource and if successful respond with a 'SUCCESS' LRM result. Only then will the HA Manager acknowledges this by adding the running flag to the HA resource's state.
