service does not handle multiple engine workers

[Angus Salkeld]

All the Service queries are based on host&binary if num_engine_workers>1 this logic breaks down.
Every next worker will overwrite the first service's data.

I have num_engine_workers=3 and yet:

    Don't assume that there is one service per host

    When we have multiple workers the service info is incorrect.
    This patch changes the logic to make a new service and
    then later delete entries that are not getting updated.
