Fee Wallet Balance Management

[tiero]

• We need to monitor the fee account with a configurable interval
• stop accepting swap request if the balance of the fee account is too low
• we need to WARN the daemon operator via logger this.
• We need to expose a FeeBalance RPC in the operator grpc interface
• We need to halt the DepostiAddres RPC if Fee account is empty

We need to monitor the fee account with a configurable interval

Since a partial implementation of this has been added with #25, I'm asking if the constructor of the crawler should be updated to meet the cited requirement or if, instead, we should add an entry to the json config file to set the crawler interval.

At first, I exposed the configuration to the user, but it actually depends only based on the network, and I think it's actually an overkill to expose that too. I would leave hardcoded for now.

ok, should we also hardcode the limit amount used to consider the fee account balance too low?

Yes, as long it is done in a single place. Consider the equivalent amount needed for circa 5 swaps.

What do you mean with "5 fees per swaps"?
