[ci, all] Adding retry mechanism when terraform command fails

Ideas

1/ Terragrunt comes with extra features that helps to solve transient errors during the pipeline execution like:

https://terragrunt.gruntwork.io/docs/features/auto-retry/#auto-retry
https://terragrunt.gruntwork.io/docs/features/auto-init/#auto-init

It requires to aadd the tool in Docker like

ENV TG_VERSION=0.55.1 \
    ARCH=amd64

RUN curl -sLO https://github.com/gruntwork-io/terragrunt/releases/download/v${TG_VERSION}/terragrunt_linux_${ARCH} && \
    mv terragrunt_linux_${ARCH} /usr/bin/terragrunt && \
    chmod +x /usr/bin/terragrunt

And also restructure the code using terragrunt.hcl (see QuickStart) ==> It seems very time costly

2/ Bash approach like explained in this article but it seems not compatible with terraform
