DataBus could be using deterministic id's

[ramonsmits]

The fileshare databus currently always generates new ID's. If the same data is passed multiple times a new blob is created. By using deterministic id's based on for example the SHA1 of its data we prevent potential expensive roundtrips.

@ramonsmits You opened up a series of data bus improvement proposals. Would it make sense to collect those in one single platform dev issue and raise it to the awareness of the squad?
