optional interval and default timeout for helmrepo

With static HelmRepository OCI, the interval become optional. Make
interval optional in the API. Introduce getters for interval, in the
form of GetRequeueAfter(), and timeout with internal default values.

HelmRepository will not have interval and timeout fields unless it's
explicitly set.
