Add "origin" to transaction

[rmeissner]

It is planned to allow Safe apps to submit transactions to the interface. As an owner of a Safe I would like to know from which service the transaction provided. For this we should add a "origin" field when sending the transaction meta to the service.

Notes:

• origin field is not part of the safe tx hash and therefore is not 100% trustworthy (maybe this should be mentioned in swagger) -> malicious owner could abuse this, but the advantages outweight this small risk
• origin field should be a string

@rmeissner I will set the maximum length of the field to 100 characters, is that ok?

[rmeissner]

In my opinion that should be sufficient

Hi @Uxio0 I just send a TX (POST) with the origin field:

and then, when I request the TX (GET) https://safe-transaction.rinkeby.gnosis.io/api/v1/safes/0xEd99E368FCD7404045D1F20cb29274ecd9Ebf428/transactions/ the origin field for the nonce 76 is null.

any Idea what can be wrong? note that I'm on Rinkeby

If you post to staging dev env you also need to get from staging dev env (and not production)
