[BangPypers] Return values

[Harish Vishwanath]

Couple of approaches:

- Break the api into two. get_stats and get_stats_consolidated. This way,
the caller who doesn't know what is your default value of "consolidated"
argument is will not be confused.
- Change the return value to be a list always. Without "consolidated" set,
it will just be [Stats], else [stat1, stat2, stat3..]
- More descriptive return value could be a dict:
{
  'consolidated': True|False
  'value' : []
}

Harish
