[Internal] Restart Cluster before Library Installation (#4384)

## Changes
<!-- Summary of your changes that are easy to understand -->
Library resource with SDK_V2 implementation waits for the cluster to get
into the running state before starting installation. This PR mimics this
behavior in the plugin framework implementation of the library resource.

Fixes
#4353
## Tests
<!-- 
How is this tested? Please see the checklist below and also describe any
other relevant tests
-->
Added a integration test.
- [ ] `make test` run locally
- [ ] relevant change in `docs/` folder
- [x] covered with integration tests in `internal/acceptance`
- [ ] using Go SDK
- [ ] using TF Plugin Framework
