Add support for interfacing with Redis

[mfelsche]

Just a thought:

We could also go super low-level and support any RESP command, if those are representable in a json-like structure. The responses also need to be encoded in some way.

While this enables all the features of redis, it might not be as easy to use. An additional std::redis std_lib library could help here.

This can be solved using the tcp_client connector on the connectors branch and a std::redis tremor-script module could help creating the RESP formats.
