why do we need new identifier in mysql locker

[fudongyingluck]

we already have an identifier for a job.

gocron/job.go

Line 754 in 63f3701

func WithIdentifier(id uuid.UUID) JobOption {

why do we need another one in the locker ? Why don't we just pass that as a parameter ?

gocron/executor.go

Line 387 in 63f3701

lock, err := j.locker.Lock(j.ctx, j.name)
