Subject: [PATCH 1/6] [Security Solution][List details page]: Manage rules -
 Selection cleared on navigation (#146121)

## Summary

- This PR, is for adding the new `Link` column Switch instead of using
table selection based on the below bug
- Addresses https://github.com/elastic/kibana/issues/145683
- Remove `Tags` duplications and filter by tags


## Problem

Manage Rules uses the `Add to Rule` component and this component under
the hood is built on top of the [In Memory
Table](https://elastic.github.io/eui/#/tabular-content/in-memory-tables#in-memory-table-selection)

Currently, this table doesn't preserve the selection when the user
navigates through the pages, which means if the user had some rules
selected on the first page, then navigated to any other page the
selection will be cleared if the user clicked on `Save` which will cause
the linked rules to be unlinked from the list without notifying the
user.

This could be solved by:

- Removing the `pagination` but the component won't fit in the `Add
Exception Flyout`
- **Add another column to the table to toggle (link/unlink) using a
[Switch
component](https://elastic.github.io/eui/#/forms/selection-controls#switch)
with making the table's row not selectable**
- Make use of the `toolsLeft` property given by the `In Memory Table` to
design a new way of linking/unlinking
 - Control the height of the `Add to Rule` component

### **We decided in the Sync meeting to try the second option as it will
give us full control over the Table data as well as we found some issues
in the selection with the search**

Not sure still what could be the quicker solution before the release,
could you please advise @peluja1012 @jethr0null

After investigating why the table removes the selected item:

[euiOnPageChange](https://github.com/elastic/eui/blob/main/src/components/basic_table/basic_table.tsx#L480)
The table under the hood, calls `clearSelection` on pagination

## Summary

Resolves https://github.com/elastic/kibana/issues/130178.

Subject: [PATCH 4/6] [APM] Mobile loading screen shows irrelevant components
 (#146476)

closes https://github.com/elastic/kibana/issues/145964

Before this was the workflow after a mobile service was clicked.:
```
service inventory -> service overview -> service mobile overview
```

Now, this is the new workflow:
```
service inventory ->  loading screen -> service mobile overview
```

cc: @boriskirov what do you think of this? We have to wait until the
service agent is fetched to decide which page to show the mobile or the
default one.

Subject: [PATCH 5/6] [ResponseOps][Flapping] detect flapping start / end, set
 flapping state (#144415)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolves https://github.com/elastic/kibana/issues/143443

## Summary

Added processing to track flapping state, and detect when an alert is
flapping.
When an alert is determined to be flapping we will log a message for
now.


### Checklist

- [x] [Unit or functional
tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html)
were updated or added to match the most common scenarios

### To verify
- Create a rule that will change between active and recovered. I like to
create a rule like `index threshold` where I can force the state to
change.
- Look at the task manager document for this rule and verify that the
`flappingHistory` in the `state` is being updated properly.
- Let the rule run and verify that if the alert is flapping in AAD,
Event Log and alert summary.

### Risk Matrix

Delete this section if it is not applicable to this PR.

Before closing this PR, invite QA, stakeholders, and other developers to
identify risks that should be tested prior to the change/feature
release.

When forming the risk matrix, consider some of the following examples
and how they may potentially impact the change:

| Risk | Probability | Severity | Mitigation/Notes |

|---------------------------|-------------|----------|-------------------------|
| Multiple Spaces&mdash;unexpected behavior in non-default Kibana Space.
| Low | High | Integration tests will verify that all features are still
supported in non-default Kibana Space and when user switches between
spaces. |
| Multiple nodes&mdash;Elasticsearch polling might have race conditions
when multiple Kibana nodes are polling for the same tasks. | High | Low
| Tasks are idempotent, so executing them multiple times will not result
in logical error, but will degrade performance. To test for this case we
add plenty of unit tests around this logic and document manual testing
procedure. |
| Code should gracefully handle cases when feature X or plugin Y are
disabled. | Medium | High | Unit tests will verify that any feature flag
or plugin combination still results in our service operational. |
| [See more potential risk
examples](https://github.com/elastic/kibana/blob/main/RISK_MATRIX.mdx) |
