make getOutstandingUploads thread-safe
This MR ensures prevents unsafe map and array accesses within the WalkFn
used by getOutstandingUploads
.
Additonally, this removes registry/storage/error.go
and it's singular function, pushError
. As pushError
was only used in two places, both in getOutstandingUploads
was was not suited to concurrent operations.
