Bug Description
We saw an instance on a scale setup where a stale UVE was being shown.
It seemed that the generator was earlier connected to b5s33, and then moved to b5s32
But part of the UVE was still being reported out of b5s33, and that part was stale.

Subject: Re: Mismatch in UVE data in introspect and analytics
Looks like a bug in the UVE aggregation logic.
This generator is connected to b5s32. The UVE value in redis in b5s32 is correct.
But it was previously connected to b5s33. The incorrect UVE is being reported out of there.
We should not be getting values for this UVE from b5s33. The generator is not on the NGENERATORS set on b5s33.
I’ll look into it some more.

contrail-collector does UVE Updates based on messages from generators.
It also deletes UVE values from redis when generators disconnect.
We saw an instance where updates seems to happen just after a disconnect.
This causes contrail-
Before the UVEUpdate script writes updates to redis, it should check that the generator
for which the update is being done is still connected (via the NGENERATORS set in redis)
