using turbolift to update helm chart version defined in buddy.works pipeline definitions

update-buddy-helm.sh

# Turbolift recipe to update helm template versions
#
# prerequisites:
# 1. https://github.com/Skyscanner/turbolift#installation
# 2. https://github.com/mikefarah/yq#install
#
# assumptions:
# 1. you have all buddy pipeline definitions under `/.buddy` directory of each repo and they all have `.yaml` or `.yml` extension
# 2. you define the helm chart version in an action of type `HELM` which has a list of `execute_commands`, and the version is passed in like `--version $version`. In other words, there's an action that looks like:
#  - action: Render k8s manifest from Helm chart
#    type: HELM
#    trigger_condition: ALWAYS
#    helm_repository_region: ap-southeast-1
#    helm_repository_integration:
#      hash_id: 5e85761fc5f225000f97dd99
#    setup_commands:
#      - helm plugin install https://github.com/hypnoglow/helm-s3.git --version 0.10.0
#    execute_commands:
#      - bash .buddy/scripts/apply_helm.sh --version 1.13.2
#    kubectl_version: v1.18.2
#    helm_version: v3.2.1

# Add list of repositories, alternatively, use gh-search to generate the list
# if this is the first time you use this, it's recommended that you add one repo to this to test it out before rolling out to all repos
