otbcli_LargeScaleMeanShift does not cleanup all temporary files

Description

otbcli_LargeScaleMeanShift does not cleanup temporary *FINAL.tif files, even if -cleanup is stated.

Furthermore, in the -mode.vector case, undocumented images *_labelmap.tif and *_labelmap_merged.tif are produced (even if -mode.vector.imfield has not been set). It looks like the two labelmap images correspond, respectively, to the unfilterd and filtered versions, but this should be documented (actually, only written if specifically so requested by an specific option). In the case of -mode.raster, the undocumented *_labelmap.tif image (corresponding to the unfiltered version) is also produced.

Steps to reproduce

otbcli_LargeScaleMeanShift.bat -in QB_1_ortho.tif -spatialr 4 -ranger 80 -minsize 16 -tilesizex 256 -tilesizey 256 -cleanup 1 -mode.vector.out regions.shp

otbcli_LargeScaleMeanShift.bat -in QB_1_ortho.tif -spatialr 4 -ranger 80 -minsize 16 -tilesizex 256 -tilesizey 256 -cleanup 1 -mode raster -mode.raster.out regions.tif
