Network API loccontrol should also handle a JSON body request

[jsccast]

As rules/add does. In other words, the following should work:

cat <<EOF | curl -s -d "@-" "$ENDPOINT/api/sys/loccontrol"
{"Libraries":{"jokes":"function funny() { return 42; }"}}
EOF

cat <<EOF | curl -s -d "@-" "$ENDPOINT/api/loc/rules/add?location=$LOCATION"
{"rule": {"when":{"pattern":{"wants":"?x"}},
          "action":{"opts": {"libraries":["jokes"]},
                    "code": "funny()+1"}}}
EOF

curl -s -d 'event={"wants":"tacos"}' "$ENDPOINT/api/loc/events/ingest?location=$LOCATION" | \
   jq '.result.values[0]'

Currently does not. If you do

curl -s --data-urlencode 'control={"Libraries":{"jokes":"function funny() { return 42; }"}}' "$ENDPOINT/api/sys/loccontrol"

instead of the first curl above, things do work.
