Feat gl cicd var scripts

Closes #232 (closed)

utils/README.md

-**Prerequisites**
+### Description
+These utility scripts avoid copying each ci variable manually which is tedious.
+- The gitlab-ci-vars-reader.py reads variables from a specific project or a pipeline (depending on the options provided) and copies them into a yaml file
+- The gitlab-ci-vars-updater.py takes a yaml file containing key value pairs in yaml format as an input. It then creates/updates project variables or pipeline variables (depending on the options provided)
+
+### Prerequisites
+```
 python -m venv ~/venvs/gitlab
 source ~/venvs/gitlab/bin/activate
