Populate segmentation model metadata for exposures and mosaics.

[schlafly]

Closes #1389

We were previously populating segmentation image metadata with filler values that were not related to the input L2 or L3 image. This PR adds code that copies the metadata from the catalogs into the segmentation images.

This now also fixes some file naming issues; the mosaic pipeline was saving the catalogs, as well as the step saving the catalogs, leading to two copies of the catalogs with different file names. Now only the step saves the catalogs. I have also changed some of the logic around the construction of the file names.

I see one issue with this so far. If I run the code with a json file I get the expected three files,
r0099101001001001001_r274dp63x31y81_prompt_F158_cat.asdf
r0099101001001001001_r274dp63x31y81_prompt_F158_i2d.asdf
r0099101001001001001_r274dp63x31y81_prompt_F158_segm.asdf

If I change the product name and rerun the pipeline I also get the expected three files,
r0099101001001001001_user_choice_cat.asdf
r0099101001001001001_user_choice_i2d.asdf
r0099101001001001001_user_choice_segm.asdf

the issue is that this seems to remove the i2d file from the run before and I now see only

ls -1 r0099101001001001001_r274dp63x31y81_prompt_F158*.asdf
r0099101001001001001_r274dp63x31y81_prompt_F158_cat.asdf
r0099101001001001001_r274dp63x31y81_prompt_F158_segm.asdf

I don't think we should be deleting files from a previous run.

The latest changes fixed the file deletion issue so LGTM

Great. regtests also passed, so I'm merging.
