Introduce .close method for redisContextFuncs

Currently, hiredis supports TCP/SSL/Unix, all of the connection types
use a single FD(int), close() is enough to close a connection. For the
further step, introduce .close method for redisContextFuncs, this
allows to close a complex connection context, for example RDMA.
