Added Delayed::Job role.
Use rubber_env in delayed_jobs args instead of fetch.
Trying to fix volume creation for non-EC2 for something like the 20th time now.
Force shut down vSphere VMs when destroying rather than waiting for a graceful shutdown, which may hang.
Merge pull request #292 from willkoehler/delayed_job_role

Added Delayed::Job role.
Preparing the 2.7.0 release.
Merge branch 'master' of github.com:rubber/rubber
Upgraded from redis 2.8.4 to 2.8.5.
Preparing the 2.7.1 release.
Added another newline for more separation.
Bundler 1.5.2 is out so we shouldn't need this hack anymore.
Persist iptables rules and have them restored upon reboot.
Upgraded from ruby-build 20131220.1 to 20140210.
Preparing the 2.7.2 release.
Be more robust and save the iptables rules immediately after we generate them.

While we hook into the network lifecycle phase, it's possible that a machine is shutdown improperly and thus our normal save hook wouldn't be executed, meaning rules wouldn't be persisted.  By explicitly saving here, we guard against that.
Preparing the 2.7.3 release.
Typo negative.
Upgraded from Redis 2.8.5 to 2.8.6.
Upgraded from Graylog 0.20.0 RC 1.1 to the final 0.20.0 release.
Only upload the iptables persistence scripts to the host that the rules are being generated for.

Without this change, the files are uploaded to every host in the cluster every time.  Since the files themselves don't change, the result is an innocuous slow down of the execution time for the rubber:setup_security_groups task; annoying, but not dangerous.
