Dragonfly v1.2.0

Another strong release for Dragonfly. Important changes include:

• Starting this release, Dragonfly will automatically save a snapshot on exit and will automatically load it back
  when it starts from the same directory. This feature has been a much-asked-for - we hope you find it useful!
  Thanks @royjacobson for implementing it!
  • As before, the snapshot's filename will contain a timestamp by default, and will not override previous snapshots. To overwrite previous snapshots, pass a custom value to the --dbfilename configuration option.
  • To disable automatic snapshots, pass an empty string to --dbfilename.
    Thanks @royjacobson !
• Replication stability improvements - thanks to @adiholden
• Lots of performance and stability improvements around PubSub - @dranikpg
• Lots of performance improvements around Lua scripting and transactions. @dranikpg
• Support for IPv6 - @royjacobson
• Automatically recognize container limits when deducing maxmemory and number of cpus: @talbii
• Json improvements by @iko1
