Execute Ansible-vendor tracked runs in stack concurrent

As a platform engineer, we are building a platform (currently in proof-of-concept stage) that uses Ansible-vendored Spacelift stacks to execute Ansible playbooks. These stack runs are triggered by orchestration via API such that each stack run executes against one EC2 instance as they are launched. Due to the blocking nature of stack runs, this limits the stacks ability to run multiple Ansible playbooks concurrently for a stack. Tasks are not a valid alternative as they do not provide any benefit to the resource/host configuration management natively built into Spacelift stacks.

Jubran Nassar is familiar with our use-case.

If we end up selecting Spacelift as our tool for our platform, this will be important to solve, but marking as nice to have for now. We should know more in the next few weeks.
