Review comment:
> This PR changes way too many files. I didn't look at all of them. But
it should have only changed 2 or 3.
> I'm not sure I like this change because now we have the parameters in two
places. We still have the switch statement in InfoExecutor that checks for each
one, but now we also have a list of them in another place
(ALLOWED_INFO_COMMANDS). The other confusing thing is that the INFO command
does allow other keywords it just ignores them. In native redis "INFO foobar"
does not give an error but just returns nothing. But by adding a
RestrictedInputValuesParameterRequirements to INFO it makes me think that any
other params would cause an error.
I'll double check, but the large number of files changed should be the
result of my moving the RedisConstants class into a new subdirectory (because
there is now another constants files to hold specifically allowed parameters ,
and it seemed to make sense to group them together). To be addressed below,
I did forget to make the change to allow an error mesg for the class to be
passed in as a parameter. As you say, for info, the error mesg will just be an
empty string, but other commands can pass in other other err msgs as is
appropriate to match native redis behavior.
I still like having the logic for the commands in the executor for now. I
see your point about the list of allowable commands being in 2 places.
Ultimately I would like to use a singleton enum, but wasn't able to figure out
how to make that work without some more playing around (let me know if you have
thoughts)
