[Archive Migration][Partial] discover apps-home

[wayneseymour]

Comes from #102827

Helps with #108503

Unload the shakespeare data in the previous suite,
and replace the ui settings with an empty object literal,
so to prepare the home suite to run from a clean state.

Additionally, set the default index to logstash-* in
the home suite.

Only include the changes under the
test/functional/apps/home folder.

No need to include a mention for me in the description. It results in me getting a notification for every update to this PR. If you need a review, or have a question - then feel free to include a mention. Thanks.

LGTM but if you wouldn't mind adding the one additional cleanup step.

[LeeDr]

minor request to also add this here. I'm sure we don't do it everywhere but since there's a call to .replace({ defaultIndex: 'logstash-*' }); it's probably best to clear it out too;

await kibanaServer.uiSettings.replace({});

[LeeDr]

but now I'm also wondering if unloading the kbn_archive unloads the config saved object? That's where the default index pattern is saved. You could check by looking in Advanced Settings after this test runs and see if it's set.

[wayneseymour]

Totally!

Ok, so I've been having issues starting the ftr server, for the last few days.
That said, I was able to use the saved objects info cli call.
After dropping out most of the test, and leaving the before and after calls in place (I also added the ui settings replace you asked for above), I got this:

node scripts/saved_objs_info.js --esUrl http://elastic:changeme@localhost:9220 --soTypes
 succ
      ### Saved Object Types Count: 6
      [
        {
          doc_count: 5,
          key: 'canvas-workpad-template'
        },
        {
          doc_count: 1,
          key: 'apm-telemetry'
        },
        {
          doc_count: 1,
          key: 'config'
        },
        {
          doc_count: 1,
          key: 'core-usage-stats'
        },
        {
          doc_count: 1,
          key: 'event_loop_delays_daily'
        },
        {
          doc_count: 1,
          key: 'space'
        }
      ]

So, the config count so type count, is 1.

I think that means we are good. Your thoughts sir? @LeeDr

Also, in case you were wondering, when I run the call just after staring the ftr server, I get this:

node scripts/saved_objs_info.js --esUrl http://elastic:changeme@localhost:9220 --soTypes
 succ
      ### Saved Object Types Count: 4
      [
        {
          doc_count: 5,
          key: 'canvas-workpad-template'
        },
        {
          doc_count: 1,
          key: 'apm-telemetry'
        },
        {
          doc_count: 1,
          key: 'config'
        },
        {
          doc_count: 1,
          key: 'space'
        }
      ]
