lib/storage: return back filter arg to getMetricIDsForTagFilter function

Browse Source 
The filter arg has been removed in the commit c7ee2fabb8
because it was preventing from caching the number of matching time series per each tf.

Now the cache contains duration for tf execution, so the filter shouldn't break such caching.
