DM-29857 implements scripts for regenerating repositories from scratch, as well as individual scripts for each step. However, the scripts for ap_verify_ci_hits2015 and ap_verify_hits2015 are redundant, in that the CI script reprocesses a subset of the HiTS data from scratch. This adds about 10 hours of unnecessary runtime to any update of both repositories.

Add a way for an update of ap_verify_ci_hits2015 to reuse the collections created for updating ap_verify_hits2015; this may be as simple as adding an optional dataset filter to the CI ingest scripts' CLI.
