Release 16.03

• Update galaxyFS to include Galaxy 16.01 release.
• Add advanced autoscaling controls. A user can now specify how long to allow
  jobs to wait in the queue for, how many jobs to maintain in the queue and
  by how many nodes to scale.
• For AWS, added ability to specify volume IOPS (either via iops user data or
  by entering your IOPS number on launch.usegalaxy.org). This allows to go
  from previous 40-200 IOPS to max 20,000 IOPS now.
• On AWS, built a new AMI (ami-b45e59de) with support for EBS-optimized
  instances.
• For AWS, added ability to launch clusters into non-default VPC subnets via
  launch.usegalaxy.org.
• When sharing a cluster with a custom galaxyIndices file system snapshot,
  make sure it gets shared as well (thanks to @hackdna for reporting the bug).
• Ensure the PostStartScript does not run before all the other services have
  been added (thanks to @hackdna for reporting the bug).
• Several updates for starting ClouderaManager (thanks to @ddavidovic).
