Fix redis-cli carriage-return in output (#508)

* redis-cli. Fix output with --raw option

Prevent TTY output format if -r or --raw flags are present. This is
necessary to avoid $'\r' in the output, that breaks shell scripts.

* redis-cli. Use same Redis image version of core

core/imageroot/usr/local/sbin/redis-cli
