Closes #1715
With this PR, instances in AWS fleets with
placement: cluster
will be grouped in cluster placement groups to provide better connectivity.Note that placement groups are not used when running multi-node tasks without first creating a cluster fleet. (We'll see if it should be implemented too).
Fleet example:
The dstack server creates and deletes placement groups transparently for users. A placement group is created when the first fleet instance is provisioned and deleted by a background task after the fleet is deleted and there are no more instances in the group.
