v2: Feature Request - expose a method for add lifecycle hook

[kcmvp]

right now life cycle hook can only be set when build a container as below
`injector := do.NewWithOpts(&do.InjectorOpts{
HookAfterRegistration: func(injector *do.Injector, serviceName string) {
fmt.Printf("Service registered: %s\n", serviceName)
},
HookAfterShutdown: func(injector *do.Injector, serviceName string) {
fmt.Printf("Service stopped: %s\n", serviceName)
},

Logf: func(format string, args ...any) {
    log.Printf(format, args...)
},

})`

my case is that I am using do as DI container build some basic infra in the group for other projects. it's obvious that other teams(projects) also need hooks for project specific design. I export the DI but they can not register hook.

proposal:
if HookAfterRegistration and HookAfterShutdown are slcie of functions and di expose a new method to add a new hook method then it will work in my case

of course there is gotcha: this new added method which for adding hook will throw error when the DI is not emtpy

thank you!

I agree.

Let's change that before v2 release. A slice of hooks might be a breaking change in container options.
