How Has This Been Tested?

1. Built the deb packages and applied to my local env.
2. Then, deployed a new VM and ensured that the new option was available at the Metrics tab

Pull Request Overview

This PR adds an auto-refresh control to the VM Metrics tab, letting users pick refresh intervals (None, 5s, 30s, 1min, 5min) and automatically re-fetch stats. It also externalizes hard-coded duration labels into i18n keys.

• Switched the “1 hour” label to use label.duration.1hour (and added corresponding locale entries).
• Added a select dropdown bound to refreshTime with options for different intervals.
• Introduced refreshTime and refreshIntervalId data fields, a calculated reaction to interval changes, and an unmounted hook to clear timers.

• [nitpick] The data property 'refreshTime' is ambiguous (it represents milliseconds). Consider renaming to 'refreshIntervalMs' for better clarity.

refreshTime: '0',

• There are no tests covering the auto-refresh dropdown behavior. Consider adding unit or integration tests to verify interval selection, fetch triggering, and interval cleanup.
