Write a `nodes info` output parser that doesn't rely on treating it like YAML

[beautifulentropy]

Parsing of Redis Nodes Info is currently done by adding a little whitespace after each : and then parsing it to a struct as YAML. This is kinda hacky and could have some unintended side-effects as YAML is more expressive than Redis Nodes info. Write a parser that handles this using reflect to parse the result of each key to a string and value to a string or an int.
