## Summary

Excluded deprecated features from solution visibility.

## How to test
1. Change the solution from `classic` to `observability` for the very
first time in the default space.
Make sure the response of the active space `GET
internal/spaces/_active_space` doesn't contain deprecated features.
(`siem`, `siemV2`, `securitySolutionCases` and `securitySolutionCasesV2`
were deprecated, so only `siemV3` and `securitySolutionCasesV3` should
be on the list)
```
{
    "id": "default",
    "name": "Default",
    "description": "This is your default space!",
    "color": "#00bfb3",
    "initials": "D",
    "imageUrl": "",
    "disabledFeatures": [
        "siemV3",
        "securitySolutionCasesV3",
        "securitySolutionAssistant",
        "securitySolutionAttackDiscovery",
        "securitySolutionTimeline",
        "securitySolutionNotes",
        "securitySolutionSiemMigrations"
    ],
    "_reserved": true,
    "solution": "oblt"
}
```
2. Change the solution back to `classic` and enable all security
features.

3. Update the space and go back to Edit Space page.
3. Make sure the enabled features counter is correctly displayed in the
UI.
