Execute "es-node -v" is a slower (4s) than excepted (less than 1s)

Execute "es-node -v" is slower than expected, that is because our Flags are implemented in different packages (flags, eslog, signer, miner) which also import other packages, so our init costs seconds to finish. the go process flow is https://pic3.zhimg.com/80/v2-ca6f92e42e1a1e75051f6af121d9f5aa_720w.webp.

cmd/es-node/main.go

func main() {
... ...
	app.Flags = flags.Flags

ethstorage/flags/flags.go

func init() {
	optionalFlags = append(optionalFlags, p2pFlags...)
	optionalFlags = append(optionalFlags, eslog.CLIFlags(envVarPrefix)...)
	optionalFlags = append(optionalFlags, signer.CLIFlags(envVarPrefix)...)
	optionalFlags = append(optionalFlags, miner.CLIFlags(envVarPrefix)...)
	Flags = append(requiredFlags, optionalFlags...)
}

Solution:
Move other flags implementation to ethstorage/flags folder and reduce their import packages.
