Redis support a separate authentication module

[令照辉]

hi，all：

   Redis can support a separate authentication module?

   An authentication module that facilitates developers to meet their business needs, such as Kerberos authentication

[Viktor Söderqvist]

Sorry for double post.

Update: It is actually possible to rewrite the calls to AUTH to use your
custom auth command. You need to use command filters.

I don't know why the RegisterCommandFilter function is not visible in
the Modules API docs. At least it is in the Redis source code in
src/modules.c.
