Purging through curl

If the purge action takes longer than the timeout value (60s I think) then nginx will cut off CKAN from completing the action because it takes too long.

The work around is to log onto the machine running the CKAN container and purge using curl.

curl 'http://localhost:8080/ckan-admin/trash' -H 'Authorization: <api-token>' -H 'Referer: http://localhost:8080/ckan-admin/trash' -H 'Origin: http://localhost:8080' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.116 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded' --data 'purge-packages=purge' --compressed
