### Describe Your Changes This PR continues the implementation of integration tests (#7199). It adds the support for vm-single: - A vmsingle app wrapper has been added - Sample vmsingle tests that test the VM documentation related to querying data (#7435) - The tests use the go-cmp/{cmp,/cmpopts} packages, therefore they have been added to ./vendor - Minor refactoring: data objects have been moved to model.go Advice on porting things to cluster branch: - The build rule must include tests that start with TestVmsingle (similarly to how TestCluster tests are skipped in master branch) - The build rule must depend on `vmstorage vminsert vmselect` instead of `victoria-metrics` - The query_test.go can actually be implemented for cluster as well. To do this the tests need to be renamed to start with TestCluster and the tests must instantiace vm{storage,insert,select} instead of vmsingle. ### Checklist The following checks are **mandatory**: - [x] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). --------- Signed-off-by: Artem Fetishev <rtm@victoriametrics.com> Signed-off-by: hagen1778 <roman@victoriametrics.com> Co-authored-by: hagen1778 <roman@victoriametrics.com> Signed-off-by: hagen1778 <roman@victoriametrics.com>
