Describe sequence of states for a file and datasets

[kjellp]

Description

Include a simple overview of the states used in the new DB schema that a file and a dataset is passing through during a normal, error free ingestion.

Proposed solution

Could be placed here: COMMUNICATION -> Data Submission -> Ingestion Procedure > Ingestion Steps. Then it comes below the detailed sequence diagram of the workflow which is very related, but the new overview is only presenting the expected sequence of states for clarity (hiding additional information on who updates it etc, available in the workflow diagram).
