This pull request extends the Cluster Toolkit Telemetry collection mechanism to include the version of Terraform currently in use. By integrating this metric, the system gains better visibility into the environment configurations, ensuring that version-specific behaviors can be tracked and analyzed effectively.

Changes:

  • Telemetry Enhancement: Added support to collect and report the Terraform version as part of the telemetry data.
  • New Metric Definition: Introduced a new constant TERRAFORM_VERSION to the telemetry metadata schema.
  • Testing: Implemented unit tests for the new Terraform version collection logic, including mock-based error handling.

KINDLY NOTE THAT TELEMETRY DATA IS NOT BEING COLLECTED YET.

Code Review

This pull request adds the collection of the Terraform version to the telemetry metadata by introducing a new TERRAFORM_VERSION constant and a helper function to execute a shell command. Review feedback highlights potential performance and stability issues related to spawning external processes. Key recommendations include moving the version retrieval out of the critical section protected by a mutex, implementing a timeout for the shell execution, and mocking the version function in unit tests to ensure environment independence. Documentation improvements were also suggested.
