Add default configuration for Redis

Signed-off-by: Max Howell <max@methylblue.com>

indirect beat defunkt to the redis formula slightly, but defunkt improved it, so everyone gets credit :)

+# Redis configuration file example
+
+# By default Redis does not run as a daemon. Use 'yes' if you need it.
+# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
+daemonize no
+
+# When run as a daemon, Redis write a pid file in /var/run/redis.pid by default.
+# You can specify a custom pid file location here.
+pidfile /var/run/redis.pid
+
+# Accept connections on the specified port, default is 6379
+port 6379
+
+# If you want you can bind a single interface, if the bind option is not
+# specified all the interfaces will listen for connections.
+#
+# bind 127.0.0.1
+
+# Close the connection after a client is idle for N seconds (0 to disable)
+timeout 300
+
+# Save the DB on disk:
+#
+# save <seconds> <changes>
+#
+# Will save the DB if both the given number of seconds and the given
+# number of write operations against the DB occurred.
+#
+# In the example below the behaviour will be to save:
+# after 900 sec (15 min) if at least 1 key changed
+# after 300 sec (5 min) if at least 10 keys changed
+# after 60 sec if at least 10000 keys changed
+save 900 1
+save 300 10
+save 60 10000
+
+# The filename where to dump the DB
+dbfilename dump.rdb
+
+# For default save/load DB in/from the working directory
+# Note that you must specify a directory not a file name.
+dir /var/db/redis/
+
+# Set server verbosity to 'debug'
+# it can be one of:
+# debug (a lot of information, useful for development/testing)
+# notice (moderately verbose, what you want in production probably)
+# warning (only very important / critical messages are logged)
+loglevel notice
+
+# Specify the log file name. Also 'stdout' can be used to force
+# the demon to log on the standard output. Note that if you use standard
+# output for logging but daemonize, logs will be sent to /dev/null
+logfile /var/log/redis.log
+
+# Set the number of databases. The default database is DB 0, you can select
+# a different one on a per-connection basis using SELECT <dbid> where
+# dbid is a number between 0 and 'databases'-1
+databases 16

+################################# REPLICATION #################################
+
+# Master-Slave replication. Use slaveof to make a Redis instance a copy of
+# another Redis server. Note that the configuration is local to the slave
+# so for example it is possible to configure the slave to save the DB with a
+# different interval, or to listen to another port, and so on.
+
+# slaveof <masterip> <masterport>
+
+################################## SECURITY ###################################
+
+# Require clients to issue AUTH <PASSWORD> before processing any other
+# commands. This might be useful in environments in which you do not trust
+# others with access to the host running redis-server.
+#
+# This should stay commented out for backward compatibility and because most
+# people do not need auth (e.g. they run their own servers).
+
+# requirepass foobared
+
+################################### LIMITS ####################################
+
+# Set the max number of connected clients at the same time. By default there
+# is no limit, and it's up to the number of file descriptors the Redis process
+# is able to open. The special value '0' means no limts.
+# Once the limit is reached Redis will close all the new connections sending
+# an error 'max number of clients reached'.
+
+# maxclients 128
+
+# Don't use more memory than the specified amount of bytes.
+# When the memory limit is reached Redis will try to remove keys with an
+# EXPIRE set. It will try to start freeing keys that are going to expire
+# in little time and preserve keys with a longer time to live.
+# Redis will also try to remove objects from free lists if possible.
+#
+# If all this fails, Redis will start to reply with errors to commands
+# that will use more memory, like SET, LPUSH, and so on, and will continue
+# to reply to most read-only commands like GET.
+#
+# WARNING: maxmemory can be a good idea mainly if you want to use Redis as a
+# 'state' server or cache, not as a real DB. When Redis is used as a real
+# database the memory usage will grow over the weeks, it will be obvious if
+# it is going to use too much memory in the long run, and you'll have the time
+# to upgrade. With maxmemory after the limit is reached you'll start to get
+# errors for write operations, and this may even lead to DB inconsistency.
+
+# maxmemory <bytes>
+
+############################### ADVANCED CONFIG ###############################
+
+# Glue small output buffers together in order to send small replies in a
+# single TCP packet. Uses a bit more CPU but most of the times it is a win
+# in terms of number of queries per second. Use 'yes' if unsure.
+glueoutputbuf yes
+
+# Use object sharing. Can save a lot of memory if you have many common
+# string in your dataset, but performs lookups against the shared objects
+# pool so it uses more CPU and can be a bit slower. Usually it's a good
+# idea.
+#
+# When object sharing is enabled (shareobjects yes) you can use
+# shareobjectspoolsize to control the size of the pool used in order to try
+# object sharing. A bigger pool size will lead to better sharing capabilities.
+# In general you want this value to be at least the double of the number of
+# very common strings you have in your dataset.
+#
+# WARNING: object sharing is experimental, don't enable this feature
+# in production before of Redis 1.0-stable. Still please try this feature in
+# your development environment so that we can test it better.
+shareobjects no
+shareobjectspoolsize 1024
