Ingestor test

adding CI test for the ingestion ( preprocessing part)

I would comment on this. If we want to have it a full pipeline test, we should watch if also registrar registers it, not only if preprocessor puts it into bucket. After merge of redis-statuses branch, for that to test, we can watch (with some reasonable timeout, so we dont wait forever in case of failure) for item appearing in register-success_set via redis-cli instead of sleep 90

example:

docker exec -it $(docker ps -qf "name=emg-pvs_redis") redis-cli SISMEMBER register-success_set "urn:eop:KGS:K3_20160101113014_19339_02281264_L0F_28E2"

mentioned in commit 3afcf0bb
