Migrate explore team API calls to useSearchStrategy.

[machadoum]

Convert existing explore team API calls to useSearchStrategybecause of issue #132703 .
This ticket includes users, hosts, network, and overview pages.
We don't need to migrate KPIs because they will get converted into Lens visualizations.

This won't have any UI changes, we just need to make sure each component is rendered correctly on the page.
More verification details can be found in each PR listed below.

useSearchStrategy should use rtk query, having it observable based will have the same performance problems as we saw in 8.2.1

[machadoum]

We have addressed the performance issue on use_observable here: #132703

I added security_solution/public/common/containers/matrix_histogram/index.ts to the list. The APM performance monitoring is being implemented in the useSearchStrategy hook, so it would be nice to migrate the histograms to track them as well.

@angorayc Will the useMatrixHistogram be migrated in another issue? Or why has it been removed from the description list?
