Readonly retry.Params and deprecate *Ln methods in logger

[name212]

deprecate *Ln methods in logger

Remove next methods from retry.Params:

WithName(n string) Params`
WithAttempts(attempts int) Params
WithWait(wait time.Duration) Params
WithLogger(logger log.Logger) Params

Now retry.Params is readonly now. It needs to prevent change in usage. For example we pass to function Params and rewrite params in original object before run loop. It it incorrect, to prevent it we do Params readonly
