Adjust fallback selection parameters 
Avoid selecting fallbacks that change their IP addresses too often.

Select more fallbacks by ignoring the Guard flag, and allowing lower
cutoffs for the Running and V2Dir flags. Also allow a lower bandwidth,
and a higher number of fallbacks per operator (5% of the list).

Implements ticket 24785.
