Some systems may choose to allow non-aws compliant bucket names and/or handle the bucket naem validation in the backend instead. This adds the option to turn off the strict bucket name validation checks in the frontend API handlers. When frontend bucket name validation is disabled, we need to do sanity checks for posix compliant names in the posix/scoutfs backends. This is automatically enabled when strict bucket name validation is disabled. Fixes #1564
