Currently the user has no way of knowing that the metadata cache file has been leveraged apart
from comparing the time which could be influenced by other factors.

It would be helpful while debugging to know whether or not the cache has been leveraged. This
information can be added to one or a combination of the below places
    1. Profiles
    2. Explain Plan Output
    3. Log files
