Create a separate RedisCache constructor which supports password and SSL enabled connection to Redis clusters. It will be consumed by services that wish to use Redis cache instead of instance based memcache to implement caching. Current cluster settings are non-SSL which do not use password.
This change is in response to the bug filed osdu/platform/system/storage#34 (closed). The bug may be filed specifically for Azure bug this is a generic connection change
Will follow up with changes in services after this is merged
