nixos/redis: add option services.redis.servers.*.group

previously if you set the "user" option and did not create a group
account with the same name the module would create a service that would
fail to start.

with this change:
- the module is more explicit about this behaviour
- you can configure the group directly, so that you're not forced to a
  particular user/group structure
- you can read the group name used by the redis service. this is useful
  for giving other services permission to use the redis socket.
