test(e2e): Hydrator's e2e tests all fail when run with `make test-e2e`

[dudinea]

When the e2e tests are run in a container (with make test-e2e command)
all the Hydrators's tests fail.

Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

To Reproduce

• Run make start-e2e
• Run make test-e2e
• See Hydrator's tests fail when the created applications fails to get synchronized within given timeout.

The error in the app manifests is:

Failed to hydrate: failed to commit hydrated manifests: rpc error:
        code = Unavailable desc = dns: A record lookup error: lookup argocd-commit-server
        on 127.0.0.11:53: server misbehaving

Expected behavior

Hydration should complete successfully, the tests should Pass

Version

latest Argo CD (master branch)
