Angular-cli: The analytics prompt shouldn't run in CI environments

[mattlewis92]

🐞 Bug report

Command (mark with an x)

npm install

Is this a regression?

Yes, the previous version in which this bug was not present was:
v7 and below

Description

When upgrading to v8 the analytics prompt breaks CI as it hangs infinitely waiting for the user to choose to enable it or not

🔬 Minimal Reproduction

Run npm install on a v8 cli project on CI. For example: https://travis-ci.org/mattlewis92/angular-calendar/builds/538499347

Attempting to disable analytics on the project then fails as the config it adds to angular.json is invalid

ng analytics project off

Anything else relevant?

The is-ci package could be used to disable that prompt on CI envs: https://www.npmjs.com/package/is-ci

The analytics config needs to be added to the schema so it can be disabled at the project level

The workaround for now is to add this to travis.yml

before_install: npx @angular/cli analytics off

You can set this flag in your CI to disable the analytics. We'll work on fixing this in the next patch release.

Awesome, thanks @mgechev! btw it might be worth documenting the NG_CLI_ANALYTICS variable here: https://angular.io/analytics

I also have this issue. For info: it appeared during the CLI beta phase, then was fixed (it was OK in CLI v8.0.0-rc.4), and is here again in v8.0.0, so a commit between v8.0.0-rc.4 and 8.0.0 reintroduced this issue.

Still having this issue. I'm currently using v8.0.6 and building on concourse's CI. See screenshot below.

The issue above is taking place when the CI process is installing dependencies. We have tried flipping an env variable to have the CLI not prompt this message with no luck
