db_redis: re-do appended commands after reconnect

Since hiredis sends out the pipelined command only after
calling redisGetReply(), we need a mechamism to queue up all
appended commands, so we can re-queue them once the connection
is re-established.

This commit introduces a redis command queue used for pipelined
commands to re-do all appended commands in case of a connection drop
(which typically happens in db-mode write-through with very low
traffic, where redis would close the connection due to inactivity).
