* Add missing CHANGELOG entry * Mirror fix to static mode (cherry picked from commit 7da5726)
) * Agent Management: Introduce support for template variables - This change allows managing template variables for remote configuration on a per-agent basis. - Both base configurations and snippets can be interpreted as templates and evaluated at load time with the provided template variables. - Templates must follow go's `text/template` syntax. - This greatly increases the flexibility and reusability of snippets. - Template evaluation has been tested in different scenarios and seems really robust. If the variables defined in the template cannot be resolved (even nested ones), and empty string is rendered instead. - Note: templates are only evaluated when the `template_variables` field within the `agent_metadata` remote config field is non-empty. - Note: this feature only applies to static mode. * Improve naming * Check error for template execution * Add tests - Tests different scenarios, including: - Referencing non existing nested objects - Conditionals - Ranges - Character escaping * Update CHANGELOG * Always evaluate templates - This is required because certain agents might start before their labels are synced. If some of the snippets assigned to them contain template variables, loading the config will fail. * Add test for template inside a template - Templates inside templates must be escaped using backticks to avoid them being evaluated by the snippet template execution * Move feature to the next release in CHANGELOG * Document templating functionality * Fix doc (cherry picked from commit d388f94)
