Resolve "getStatus of IDS does not accept multiple dataset ids conveniently"

Closes #347 (closed)

This replaces 3 endpoints:

/catalogue/:sessionId/dataset/id/:datasetIds/status
/catalogue/:sessionId/data/download
/catalogue/:sessionId/dataset/restore

by

/ids/:sessionId/datasets/status
/ids/:sessionId/data/download
/ids/:sessionId/datasets/restore

It also modify the .env needed for graylog:

GRAYLOG_ENABLED= # 0 or 1 if activated
GRAYLOG_HOSTNAME= # this indicates the hostname origin of the log
GRAYLOG_PORT=
