    **Fixed** xDS may not be updated when there are multiple destinationRules for a service are merged.
9
    In this case the merged rule does only record one name/namespace pair of all the destinationRules.
10
    however this meta is used to record config dependencies of a sidecar.

12
    In this fix, we inroduce a new struct `consolidatedDestRule` and record all the destinationrules' meta.
13
    And then we will not miss any destinationRule dependency.
