    This is breaking a lot of the collocated servers.
    
    Run the examples, run the whole testsuite. 
    
    I just ran the examples and the colocated ones are broken after this.

>          Components: Broker
>    Affects Versions: 1.5.2

>
> With live-only ha policy, two brokers can be started at the same time even if they are using the same data store.
> Data store should be exclusive to each broker, otherwise the data will get messed up. 
> This can be fixed using the shared store live activation, namely using the FileNodeManager to get exclusive lock before starting/init the broker.
