    Description

      Identify which Catalog and Statestore instance is active from the web debug endpoint.

      For the HA, we should improve the label on catalog and statestore web response to indicate "Active" instance.

      On the main page we could indicate "Status: Active" or "Status: Stand-by". We could probably add the status at the top of the main page before "Version" .  The current details as output of a curl request on port 25020:

        <h2>Vers<span id="v">i</span>on</h2>
        <pre id="version_pre">catalogd version 4.0.0.2024.0.18.0-61 RELEASE (build 82901f3f83fa4c25b318ebf825a1505d89209356)
      Built on Fri Mar  1 20:13:09 UTC 2024
      Build Flags: is_ndebug=true  cmake_build_type=RELEASE  library_link_type=STATIC  </pre>
      <!-- The space after  is necessary to add a space between each flag when
      this page is rendered -->
        <h2>Process Start Time</h2>
      ......
      

      Corresponding curl request on statestored on 25010:

        <h2>Vers<span id="v">i</span>on</h2>
        <pre id="version_pre">statestored version 4.0.0.2024.0.18.0-61 RELEASE (build 82901f3f83fa4c25b318ebf825a1505d89209356)
      Built on Fri Mar  1 20:13:09 UTC 2024
      Build Flags: is_ndebug=true  cmake_build_type=RELEASE  library_link_type=STATIC  </pre>
      <!-- The space after  is necessary to add a space between each flag when
      this page is rendered -->
        <h2>Process Start Time</h2>
      

      Catalogd active status can be figured out using the catalogd metric: "catalog-server.active-status"

      Statestored active status we probably don't have a metric so should add a similar metric and use that to determine status.
