[BB-5230] Implements the Grove CLI package with a Test Pipeline

Description

The MR deals with creation of the files and folder structure for the proposed grove-cli[1] along with configuration for automatically running linting and testing checks on Gitlab CI using Black and PyTest.

It also implements the grove new <instance_name> command that can be executed by calling CLI script.

Testing information

Testing the Gitlab CI setup for the CLI

• Make changes to files and commit
• Push to Gitlab
• Gitlab CI pipeline will should start with stages "CLI Lint" and "CLI Test"

Previous Runs for example: https://gitlab.com/opencraft/dev/grove/-/pipelines/425266371

Test the CLI

As Grove is used as the sub-module of Grove Template, testing can be done by cloning the Grove Template repository and copying the files.

# Clone the template as a new cluster - my-cluster
git clone git@gitlab.com:opencraft/dev/grove-template.git my-cluster

# Let's remove the sub-module and replace it with this branch
cd my-cluster
rm -rf grove

# Clone Grove and checkout to this branch
git clone --branch arunmozhi/bb-5230-grove-cli  git@gitlab.com:opencraft/dev/grove.git

# Setup a virtual environment for testing
python3 -m venv venv
source venv/bin/activate

# install the dependencies for the cli
pip install -r grove/tools-container/grove-cli/requirements.txt

# Set the Project directory to the "my-cluster" directory
export CI_PROJECT_DIR=.

# Test the grove-cli "new" command
python3 grove/tools-container/grove-cli/cli.py new my-instance

Now a copy of the folder defaults should be available inside the instances folder under the name my-instance

$ ls instances
example my-cluster

None

Other information

The GitLab CI setup for PyTest is also setup with Coverage, so test coverage will be available in the MR's diff view (including this MR) sample
