Update the way the Redis host(s) can be configured for the tests.

There is now a single property : redis-hosts.
This property must contain at least 2 host definitions of the form "host:port" (comma separated).
Sharding tests need 2 hosts ...

If this is not the case, the default value used is "localhost:6379,localhost:6380".
Tests that required one host are using the first definition.
