Code Issues Proposed changes

Add sorting_method to swift proxy config as needed

Browse Source 
When read_affinity is used and sorting_method is not used warnings
are generated in the swift proxy log indicating that the
read_affinity is not being respected. When read_affinity is specified
this change sets the sorting_method to affinity automatically, and
otherwise uses a configured value which defaults to shuffle.

Note that write_affinity does not respect sorting_method and follows
a different code path and does not issue warnings in logs when used
without sorting_method.
