🚀 Update variables reconciliation logic to reduce number of API calls

[arybolovlev]

Description

This PR introduces changes to variables reconciliation in the workspace controller

• Extend status with variables status:

status:
  variables:
    - category: terraform
      id: var-a1hnPzjknedvkoky
      name: username_length
      valueID: 7269bfbb3a64c5a26effe18028e5362f989cf71905038f90da60eefa619b8946
      versionID: 951e711fc7b19146cafedeefb9b092d75c0497420876bef00fa17d57f7b27e20

status.variables.[*].versionID and status.variables.[*].valueID are hashes of a variable on the HCP Terraform and HCP Terraform Operator sides, respectively. Tracking these values allows variables to be updated when they have changed. Previously, sensitive variables were constantly updated during each reconciliation due to their nature, resulting in unnecessary API calls.
