Pass the hardcoded jitter factor explicitly instead of relying on RetryInterceptor's default

RetryInterceptor is generated code we don't maintain, so its internal
DEFAULT_JITTER_FACTOR is free to change on a future regeneration.
Passing Optional.of(RETRY_JITTER_FACTOR) from VaultClient keeps the
0.2 hardcode visible and owned in our own code instead of implicitly
inherited by passing Optional.empty().
