Cluster placement groups

Instances of AWS cluster fleets are now provisioned into cluster placement groups for better connectivity. For example, when you create this fleet:

type: fleet
name: my-cluster-fleet
nodes: 4
placement: cluster
backends: [aws]

dstack will automatically create a cluster placement group and use it to provision the instances.

On-prem and VM-based fleets improvements

• All available Nvidia driver capabilities are now requested by default, which makes it possible to run GPU workloads requiring OpenGL/Vulkan/RT/Video Codec SDK libraries. (#1714)
• Automatic container cleanup. Previously, when the run completed, either successfully or due to an error, its container was not deleted, which led to ever-increasing storage consumption. Now, only the last stopped container is preserved and is available until the next run is completed. (#1706)

Major bug fixes

• Fixed a bug where under some conditions logs wouldn't be uploaded to CloudWatch Logs due to size limits. (#1712)
• Fixed a bug that prevented running services on on-prem instances. (#1716)
