fix: Correct common lib repo URL, rename exporter template (#19)
* fix: Correct common lib repo URL, rename exporter template - Reverted common library repository URL in Chart.yaml to https://bjw-s-labs.github.io/helm-charts/. - Ensured helm dependency commands are run after adding repositories. - Renamed exporter template from exporter-deployment.yaml to exporter-controller.yaml to better reflect its new role with common library. Note: Full helm lint/template validation with dependencies was not possible in the automated environment due to issues with dependency file persistence in the sandbox. * fix: Integrate bjw-s/common library for exporter controller - Corrected bjw-s/common library repository URL in Chart.yaml to the traditional HTTPS URL and ensured dependencies are fetched. - Renamed exporter template to exporter-controller.yaml. - Updated exporter-controller.yaml to correctly use `bjw-s.common.render.controllers` for rendering. - Refined the context passed to the common library to include Values, Chart, Release, and Capabilities, and initialized expected top-level keys (global, defaultPodOptionsStrategy) in the Values. - Ensured image.tag is defaulted to Chart.AppVersion in the template data to pass common library validations. - Helm lint and template commands now pass successfully for both Deployment and DaemonSet configurations of the exporter. * fix: Set dependencies.install to false by default - Changed the default value for `dependencies.install` to `false` in values.yaml. - Updated comments to clarify that users should explicitly enable it if they need the chart to install a Prometheus Operator dependency. * fix: Update CI workflow to add Helm repositories and build dependencies * hotfix: Pass .Template to common lib for tpl context - Updated exporter-controller.yaml to include .Template in the dict passed to the bjw-s.common.render.controllers include. - This is to resolve a 'cannot retrieve Template.Basepath' error encountered with the tpl function in older Helm versions (like v3.10.0 in CI) when the tpl context does not contain the .Template object. --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>pull/20/head v0.2.0
