Comment 2 for bug 1677661

2 more commits pushed.

First commit removes the duplicate batch targeting code that lived in Utils::HoldTargeter, which existed before the open-ils.targeter service came to be. This includes moving the API docs into the open-ils.hold-targeter API documentation.

Second commit updates the Perl live tests to call the API instead of the now-deprecated function and to test the new --soft-retarget-interval option (removing --skip-viable).
