Azure Orch Updates

[JONBRWN]

Orchestration updates mainly related to Azure

• updates to Ubuntu Bionic as default
• updates installation instructions certain tools/packages for Bionic
• updates ponyc to pin to 0.29.0
• adds sync-dir make command which allows for syncing local directories to cloud
• disables timesync in azure which was causing issues when used with ptp

I think most have successfully used this branch to launch instances in Azure at this point, merging to master to avoid having this become stale ref #
