Feature Request: Move gas cap setting to config file

[tamashi095]

We are running a backend service which frequently requires larger gas coins (4-5 SUI). After some debugging, I found out our issues are due to sui-gas-pool rejecting reservation requests larger than 2 SUI in /src/rpc/rpc_types.rs.

pub const MAX_BUDGET: u64 = 2_000_000_000;

It would be great if this could be moved to the config file so users can specify their own max budget! For now, I've forked the repo and changed the MAX_BUDGET.

Thanks @tamashi095, that sounds like a good thing to have. We'd be happy to get a PR in, if you feel inclined to submit one.
