Apisix-dashboard: test: clean the temporary data in etcd at the end of test case

[membphis]

the current way: https://github.com/apache/apisix-dashboard/blob/96e3ad1ec87f35d52d75f0a560dc152843e21e23/api/test/e2e/route_test.go#L227-L260

The current way is to completely depend on the developer and bring extra work to the test case maintainer.

we need a common way to clean all of the temporary data in etcd after running the test cases of each file.

I think this feature is useful. The E2E test cases are unstable, I think this feature will improve the stability of E2E testing.

@nic-chen @ShiningRush do you think we can implement this feature at milestone 2.2?

[ShiningRush]

It is useful and easy to implement with go's TestMain, We can ensure etcd is fresh before start test.

@gxthrj @nic-chen do you know TestMain? Any suggestions?

[nic-chen]

I think we need to clear ETCD data without distinction before or after running test, by TestMain.

[gxthrj]

The TestMain way is a test suite like ginkgo, we can use it make struct more clear, but I still like ginkgo mode.

Sorry for I am late. I think we can do this work when we use ginko framework.
As far as I know, we will use ginko framework in M2.4, so this will be solved at that time.
