Integrate fault injection flow

[ricted98]

Add a fault injection flow support in the PULP cluster.

• Design specific net extraction utilities are placed in scripts/fault_injection_utils/pulp_extract_nets.tcl
• For each desired test, a configuration file for the fault injection simulation is added (refer to pulp-platform/regression_tests@28823bc)
• The "bulk" of the injection scripts is added as a submodule pointing to pulp-platform/InjectaFault@84ddcff

In particular, the TCL scripts used to run the simulation look for env variables named FAULT_INJECTION to toggle fault injection and FAULT_INJECTION_SCRIPT to source the top level script responsible for invoking all the different subroutines for the fault injection.

This draft PR is subordinate to the merge of #54 and can be considered a WIP.

So far OK, but I think this is still WIP (I see it marked as draft).

[ricted98]

Force pushed to rebase it on astral. I believe in a short time I will convert this PR from draft to review-ready.

[yvantor]

Just one additional comment, other than that it looks good!

[ricted98]

This PR is paired to pulp-platform/regression_tests#12 to enhance also the regression tests.

This PR was merged! If this is ready we can merge this as well.

[ricted98]

Do we want to add a fault injection test to the CI? Otherwise, I think it is ready to merge.

[yvantor]

@ricted98 Yes! We should have one test in the CI at least used as an example to replicate the flow.

[ricted98]

Done. Everything should be now integrated also in the CI.

[yvantor]

I merged also the regression tests PR. Closing this!
