objecter: set pgls start_epoch field

For each pg, start out with start_epoch = 0 in the first request.  For
subsequent requests, set it to the first reply's epoch.  This forces the
OSD to ignore our cookie and "restart" if the pg mapping changes and there
is a possibility of incomplete results.

The price we pay is the possibility of duplicate results.

Fixes: #1030
