Relocates client.ParseLabelSpec to lib/utils/parse. This results in a net 5MB reduction in the weight of lib/config. This may not have a correlation in binary size since lib/client is heavily consumed by other packages. ```bash $ goda cut './lib/config:all' | rg '^github.com/gravitational/teleport/lib/client\b|^ID' github.com/gravitational/teleport/lib/client InDegree=1 Cut.PackageCount=75 Cut.AllFiles.Size=5.3MB Cut.Go.Lines=129512 ```
