This change primarily changes the type of the api_objects yaml structure
to a map, which allows for additional objects to be added by values
overrides (Arrays/Lists are not mutable like this)
Also, in the previous change, some scripts in HTK were modified, while
other were copied over to the Elasticsearch chart. To simplify the chart's
structure, this change also moves the create_s3_bucket script to Elasticsearch,
and reverts the changes in HTK.
Those HTK scripts are no longer referenced by osh charts, and could be candidates
for removal if that chart needed to be pruned
