Logging setup and cli arg handling could be cleaner #38
Description
Logging and CLI arg handling is a bit hacky.
For instance:
- some vars defined here and reused:
relayscan/cmd/service/service.go
Line 10 in 3a3dcb2
- logging actually instantiated here: https://github.com/flashbots/relayscan/blob/3a3dcb24167078f66952ad41034124360ba6bbec/common/logging.go
Improvements:
- Switch to https://github.com/urfave/cli for CLI argument handling
- Switch to built-in logger (see also https://github.com/flashbots/go-template/blob/main/cmd/cli/main.go#L26)
