Integrate manage.py (scbackups/screstore/listbackups) and curator with the "amsterdam" commands

[Eagleman7]

Give us the ability to backup, restore and listbackups and manage elasticsearch data with the amsterdam command.

Now we have to execute:

docker exec amsterdam_scirius_1 python /opt/selks/scirius/manage.py scbackup
docker exec amsterdam_scirius_1 python /opt/selks/scirius/manage.py screstore
docker exec amsterdam_scirius_1 python /opt/selks/scirius/manage.py listbackups

docker exec amsterdam_elasticsearch_1 curator delete indices --prefix logstash-alert*

I can pick this up once #52 is sorted.
