Make fleet integration dashboards space aware

[Alphayeeeet]

Describe the feature:
The managed fleet dashboards should be included in different spaces. If there is an integration update, all dashboards in all spaces should be updated.
Describe a specific use case for the feature:
We have default software like apache httpd in different environments. Different applications use IIS as their base. We categorize an application in its own Kibana space. However analysts should also be able to make use of the default dashboards for standard integrations. Each one in their distinct spaces.

Hey @Alphayeeeet thank you for the issue. We're currently working on a large project to adopt full space awareness for all of Fleet + Integrations within Kibana. We've compiled a list of the known limitations and are posting public updates on the status of the project over at #175831. I'm going to close this issue in favor of that one.
