Add account_id to rpc_relay_operator_balance metric

[dalvizu]

Problem

The rpc_relay_operator_balance metric can be configured to run on different accounts. Due to a key problem for example the testnet is running from a different account than it normally is.

We use the rpc_relay_operator_balance to monitor the balance of the account, so that it doesn't run to 0 without anyone noticing. It'd be great if we had this exposed as a label in the prometheus metric as well so that we can easily tell which account must be funded.

Solution

Add account_id to the rpc_relay_operator_balance metric data

Alternatives

Asking Nana politely which account we are using :)
