Warnings during service:push in Node v14.8.0 with the CLI

**Intended outcome:**

I was pushing the schema using `service:push` to apollo studio using `npx apollo service:push --graph=tc-graph --key=service:tokenhere --variant=current --serviceName=svc-name --serviceURL=http://localhost:port/ --localSchemaFile=./path/to/GQLFile.gql` and it was supposed to work without any warnings.

**Actual outcome:**

It throws varning like this.

**How to reproduce the issue:**

I guess this has been happening with other packages as well since Node 14.x (ref: https://github.com/nodejs/node/issues/32987) and this is the PR related to it: https://github.com/nodejs/node/pull/29935

**Versions**

`apollo/2.30.3 linux-x64 node-v14.8.0`

Start by reproducing the `service:push` command from the issue with Apollo CLI 2.30.3 under Node v14.8.0, then inspect the warning shown during the push. Done means the command completes without the reported warning, or the warning's compatibility impact is clearly documented.
