version 3.4.0

• Small changes to error handling in redis pubsub.
• Add connect and read timeout options for the cloud provider http clients.
• Handle automatically accepting instance extension requests. Can be for no one, staff or everyone. Applies to individual images (configurable through admin ui).
• Update WebX Relay to 1.7.0
• Send remote desktop parameters to the cloud-init metadata (can be used to initialise a remote desktop session for the instance owner on startup).
• Add "modal" type notifications (in parallel to legacy "banner" ones). Store user acknowledgements when a notification has been read.
• Keep session Id of webx sessions active even when no one is connected. delete all sessions when an instance is deleted, rebooted or shutdown.
• Test for secondary protocol being open when getting the instance state. Use the secondary protocol when creating the guacamole tunnel.
• Add a secondary VDI protocol to the image: used for guacamole to specify the underlying remote desktop protocol (ie RDP).
• Remove optional column from ImageProtocol. Check explicitly for the VDI protocol being available in the state instance action.
• Send vdi protocol in instance state changed event (event gateway)
• Modify instance update in account instance controller to handle vdi protocol.
• Modify creation of instances with choice of vdi protocol from the client. Send default VDI protocol with Image to client. Send full ImageProtocol with Instance data to clients.
• Modify creation and edition of images to handle default VDI protocol.
• Automatically determine the instance session protocol if not explicitly set (from image or last instance session). Return protocol in DTOs.
• Add "default VDI protocol" to Image and "VDI protocol" to instance.
• Send instance session VDI protocol to web client (for display in admin sections)
