a3high single blueprint to use the tcpx patched kernel

[bytetwin]

Building custom image for a3high slurm that installs tcpx kernel, compatible nvidia and cuda drivers and then stacks up latest slurm-gcp version onto it.

The change also includes combining the earlier 3 blueprints into a single blueprint that spins up the base, builds the image and then deploys the cluster.

Added integration tests based on the new blueprint. Integration test has been tested.

Code Review

This pull request refactors the a3-highgpu-8g Slurm cluster deployment by consolidating three separate blueprints into a single, more streamlined blueprint. This new blueprint also automates the process of building a custom image with a TCPx-patched kernel for enhanced network performance. The changes significantly improve the user experience by simplifying the deployment process. The review identifies a critical issue where configuration variables are swapped, a high-severity issue in the documentation that could cause user commands to fail, and a couple of medium-severity issues related to misleading comments in the new blueprint file. Overall, this is a valuable improvement, and addressing the identified issues will make it even better.

Looks good, some sections can be removed / altered.
