Telemetry - distinction between local and remote transactions

[beniaminmunteanu]

Context

We could differentiate between remote and local transactions, and have different metrics for both.

For the 2 metrics that we have now:

transactions_total -> collected in payment>outgoing>lifecycle>handleSending. Distinction can be done by the receiver.incomingPayment.walletAddress being a local wallet address or not

transactions_amount -> collected in ILP connector telemetry middleware. Distinction can be done by the accounts.outgoing being an instaceof Peer or not. (It being Instance of Peer implies that the transaction is remote)
