Assess CI on custom AMI with pre-deployed nebari

[viniciusdc]

This exploration involves evaluating the feasibility of running our CI pipeline on a custom (AMI) that includes a pre-deployed Nebari environment (using the latest release version).

The process will use Packer to build the AMI based on an Ubuntu 22.04 image, with Ansible provisioning to configure Nebari.

The main goal of this exploration is to attempt to reduce the time it takes for our current local test deployment to successfully enter the integration tests phase. Currently, most of its time is spent deploying and preparing the kind cluster.
