number of active transformers is incorect

There are two main reasons why it this the case.
Currently the number comes from number of pods created by the transformer deployment.
We often see situations where deployment scaled up to 2000 pods but only 1000 are actually running and the rest is in pending state.
The other way this is wrong is because we have ServiceXLites that often have very large number of transformers running without being even seen by ServiceX.
