v0.9.3-rc.3

All the v0.9.3-rc.2 users should upgrade their clusters by recreating with rc.3 because of the performance issue in the controller node #199

Improvements

• Move from the deprecated m3.medium instance type to the marginally better t2.medium (#184)
• Use computed stack name to ensure node pools are nested within the cluster (#187, thanks to @icereval)
• Allow etcd cluster health check via port 2379 (#191, thanks to @jgmize)
• Setups labels following the same used on kops (#221, thanks to @gianrubio)

Fixes

• Controller node not being properly tainted (#199, thanks to @artushin)

• Report error if assets packing failed (#204, thanks to @redbaron)
• Typo in node-pools render stack message (#225, thanks to @whereisaaron)

Documentation

• Point to the node-pool documentation: (aws-experimental-features) is a dead link, but in this case the intended target seems to be the node-pool documentation. (#200, thanks to @ankon)
