[cli]: apollo service:download always uses apollo.config.js if present

[Hotell]

Intended outcome:

• CLI shouldn't merge/use by default config or there should be an opt out flag to not use config by default.

Only "dirty fix" that works for getting fresh schema and then use vscode plugin by defining localSchemaFile in config, is, to remove apollo.config before running service:download.

• make use apollo service:download --endpoint="..." my-schema.json to not use apollo.config.js if present by default.

Actual outcome:

if apollo.config.js is present, it's gonna be used for cli commands and cannot be overriden.

This causes various issues:

• if localSchemaFile is used within config file, it will throw error (file doesn't exists)
• unable to fetch fresh schema ( used for validation/compilation of types on CI. UI and API are 2 separated projects )

How to reproduce the issue:

Versions
apollo@2.6.0

Hi @Hotell! Sorry this has taken so long to look at. I think this is a problem with our documentation around configuring projects. Right now, the apollo config isn't meant to be used with more than one project. If you're using a monorepo with multiple projects under a single root, you'd need to use separate apollo.config.js files for each of those projects at their respective roots.

If I'm misunderstanding, please provide a simple reproduction repo and steps to show what's going wrong for you, and I can reopen
