redis-cli cluster import support source and target that need auth (#7994)

Browse Source 
Make it possible for redis-cli cluster import to work with source and
target that require AUTH.

Adding two different flags --cluster-from-user, --cluster-from-pass
and --cluster-askpass for source node authentication.
Also for target authentication, using existing --user and --pass flag.

Example:

./redis-cli --cluster import 127.0.0.1:7000 --cluster-from 127.0.0.1:6379 --pass 1234 --user default --cluster-from-user default --cluster-from-pass 123456

./redis-cli --cluster import 127.0.0.1:7000 --cluster-from 127.0.0.1:6379 --askpass --cluster-from-user default --cluster-from-askpass
