For our Kata UVM, we know we need at least 128MB of memory to prevent instability in the guest.
Enforce this constraint with a descriptive error to prevent users from destabilizing the UVM with faulty k8s configurations.

Note: that is likely flagged because having two headings with the same
name, even under different sections, makes it impossible to create a
canonical heading link in Markdown.
This should eventually be squashed into the node-builder commit.

This also fixes a shellcheck error and lets us require the
shellcheck-required job:

- similar to the static_sandbox_default_workload_mem option,
assign a default number of vcpus to the VM when no limits
are given, 1 vcpu in this case
- similar to commit c7b8ee9, do not allocate additional vcpus
when limits are provided

After these changes:
1. The value of the K8s runtime class memory overhead:
- Covers the memory usage from all the Host-side components (mainly
the Kata Shim and the VMM).
- Doesn't include the memory usage from any Guest-side components.
2. The value of a pod memory limit specified by the user:
- Is equal to the memory size of the Pod VM.
- Includes the memory usage from all the Guest-side components
(mainly user's workload, the Guest kernel, and the Kata Agent)
- Doesn't include the memory usage from any Host-side components.

and evaluate the components used in AKS' Pod Sandboxing and
Confidential Containers preview features. This includes the capability
to build the IGVM file and its reference measurement file for remote

node-builder: introduce BUILD_TYPE variable
This lets developers build and deploy Kata in debug mode without having to make
manual edits to the build scripts.
With BUILD_TYPE=debug (default is release):
* The agent is built in debug mode.
* The agent is built with a permissive policy (using allow-all.rego).
* The shim debug config file is used, ie. we create the symlink
configuration-clh-snp-debug.toml <- configuration-clh-snp.toml.
For example, building and deploying Kata-CC in debug mode is now as simple as:
make BUILD_TYPE=debug all-confpods deploy-confpods
Also do note that make still lets you override the other variables even after
setting BUILD_TYPE. For example, you can use the production shim config with
BUILD_TYPE=debug:
make BUILD_TYPE=debug SHIM_USE_DEBUG_CONFIG=no all-confpods deploy-confpods

node-builder: introduce SHIM_REDEPLOY_CONFIG
See README: when SHIM_REDEPLOY_CONFIG=no, the shim configuration is NOT
redeployed, so that potential config changes made directly on the host

node-builder: Fix SHIM_USE_DEBUG_CONFIG behavior
Using a symlink would create a cycle after calling this script again when

Also, I moved this block to the end of the file to properly override the final
config file.
