Satellite bw usage v3 121 (#547)
* protobuf for sending bandwidth agreements to satellite from storage nodes

* Setup process for sending agreements

* Add payer_id to db with bandwidth agreements for better sorting

* Linter errors

* Read agreements from PSDB

* Try writing message to server

* Cleanup

* Basic functionality

* Better error handelling

* Fix test

* setup config and server structure for receiving bandwidth agreements

* Resolve linter issues

* Optional commit for if we want to handle deletes all at once

* add identity to Server, add logic for receiving bandwidth messsages

* Bandwidth agreement DBX creation and integration with bw agreement endpoint
