Add link from holds to hold copy map in fieldmapper

[Jeff Davis]

The fieldmapper should provide a link from holds to hold copy map for reporting purposes. We added a custom link for this at Sitka many years ago to help some of our libraries manage recalls; I think it would be a useful feature for the broader EG community.

Working branch user/jeffdavis/lp1845238-holds-link-to-hold-copy-map adds the link to action::hold_request and action::last_hold_request:

I can verify that Jeff's patch updated the fieldmapper cleanly, but I'll leave it to someone more knowledgeable about the field mapper to do the signoff.

I confirmed that the link to the Holds Copy table is now available from the Holds Request table in the reporter. I think this will be useful. My signoff is at:

Jeff, upon looking at this - what makes the new link different from the eligible_copies link that was added via commit b3d45facd05ac505b3fde745ac18bf6829a5c4e6 back in 2012? On the face of it, the patch seems redundant.

[Jeff Davis (jdavis-sitka)]

Good catch, Galen, thanks. The commit I shared dates from 2010; I missed the fact that a link to asset.hold_copy_map had been added since then, so my branch is indeed redundant. Sorry for the noise! I'll mark this bug as invalid.
