Option types must propagage missing fields

[peczenyj]

option DisableIndentity and ContextTimeoutEnabled sometimes are not available or not propagate betweend option types.

BTW I think it is strange that exists an option CredentialsProvider but we only use in the simple case, why Universal, Ring or Cluster does not use it?

same for Limiter

       CredentialsProvider func() (username string, password string)
	// Limiter interface used to implement circuit breaker or rate limiter.
	Limiter Limiter
