udpate integration test

[suchen-sci]

We update example yaml last week (use new cluster version of yaml). As a result, primary-001 can not used alone for integration test since it will wait all clusters to start up. This pr update integration test to use single node primary easegress to do the test.

update github workflow, run test when change yaml file and shell file since these changes may fail integration test.

LGTM but just for reference we could also test 3 member cluster like this 85cf299

Thanks Samu, we may add that later. Test cluster may need some new tests. Objects like HTTPServer need open new port, so when run multiple easegress in one machine, some objects may failed to create.
