* implemented format blob cache abstraction * moved upgrade lock logic to repo/format * moved set parameters logic to repo/format * moved change password functionality to repo/format * mechanical changes * mechanical changes to react to format manager interface * get current repository format bytes instead of static * implemented format.Manager which dynamically fetches and caches latest format blob * repo changes to use format.Manager * fixed failing unit test due to different timings * reduced lock contention by using RWMutex * serve immutable parts of format without any locks * increase test timeout * fixed handling of negative validDuration The new rules are: - validDuration < 0 - ignore initial cached file, refresh every 15min - validDuration > 15min - refresh every 15 minutes - validDuration > 0 && validDuration <= 15min - refresh using provided interval (mostly used for testing)
