Secrets Manager Polling

[leoparente]

This pull request involves significant changes focused on removing the secretsmgr dependency from the configmgr package and enhancing the secretsmgr package functionality. The most important changes include updating the New function signatures, modifying the PolicyManager to handle secrets, and adding a polling mechanism for secrets in the vaultManager.

Removal of secretsmgr dependency from configmgr:

• agent/agent.go: Removed the secretsmgr dependency from the configmgr initialization and updated the New function to reflect this change. [1] [2]
• agent/configmgr/git.go: Removed the secretsmgr import and the associated sMgr field and methods. [1] [2] [3]
• agent/configmgr/local.go: Removed the secretsmgr import and the associated sMgr field and methods. [1] [2]
• agent/configmgr/manager.go: Updated the New function to remove the secretsmgr parameter and adjusted the initialization logic accordingly. [1] [2]

Enhancements to secretsmgr:

• agent/secretsmgr/manager.go: Modified the RegisterUpdateCallback to use a map of policy IDs and added a log message for when no secrets manager is specified. [1] [2] [3]
• agent/secretsmgr/vault.go: Introduced a polling mechanism for secrets and added a token lifecycle watcher to handle token renewal. [1] [2] [3] [4] [5]

Modifications to PolicyManager:

• agent/policymgr/manager.go: Updated the PolicyManager to include the secretsmgr and handle secrets within policy management. Added a callback for policy changes and updated the ManagePolicy method to solve secrets. [1] [2] [3] [4]

These changes streamline the configuration management process by decoupling the secrets management and enhancing the handling of secrets within the PolicyManager.
