[Fleet] Add a link to see Elastic Agent metrics from the Agent details

[jen-huang]

I think we can add a "View agent dashboard" button to the page header of the agent details page.

Since the header area is starting to get crowded with information and causing layout issues for agent's with long names, I'm also proposing that we move the meta information into the "Overview" panel. Some of this information already appeared there and was a bit redundant being in two places. Summary + screenshot of small changes below:

• Move status, last activity, policy, and agent version to the Overview panel
• In the overview panel, remove the "Integrations" section since they appear on the right
• Change monitor logs / metrics to read "Enabled" / "Disabled" rather than True/False.

Since 8.1 the elastic agent package is not installed by default we should probably check what to do in the case the package is not installed.

We should avoid hardcoding the Elastic Agent dashboard ID into our code. What would be the most reliable way to find the dashboard? I can't think of any better than looking up the saved object from the installed_kibana list on the epm-packages objects. What happens if there is more than one dashboard?
