When want to disable the typescriptMismatch warning on a project-basis so it only affects a particular project and the warning is automatically disabled for other developers. Hence, I want to disable it from within the angular-cli config file.

Versions.

@angular/cli: 1.4.1
node: 7.7.1
os: win32 x64
@angular/common: 4.3.6
@angular/compiler: 4.3.6
@angular/core: 4.3.6
@angular/forms: 4.3.6
@angular/http: 4.3.6
@angular/platform-browser: 4.3.6
@angular/platform-browser-dynamic: 4.3.6
@angular/router: 4.3.6
@angular/cli: 1.4.1
@angular/compiler-cli: 4.3.6
typescript: 2.5.2

Repro steps.

Setup angular project to use latest typescript.

Add this to .angular-cli.json:

    "warnings": {
        "typescriptMismatch": false
    }

run "ng build"

The output given by the failure.

@angular/compiler-cli@4.3.6 requires typescript@'>=2.1.0 <2.4.0' but 2.5.2 was found instead.
Using this version can result in undefined behaviour and difficult to debug problems.

Please run the following command to install a compatible version of TypeScript.

npm install typescript@'>=2.1.0 <2.4.0'

To disable this warning run "ng set --global warnings.typescriptMismatch=false".

Desired functionality.

When I disable the typescriptMismatch warning in .angular-cli.json I expect the warning to disappear when running ng build.

Mention any other details that might be useful.

It might be possible to disable the warning instead by setting a global flag but I want something that only affects a single project yet is shared with other developers automatically. Setting a global flag won't do that.

Currently we only support disabling it globally, but I agree it would be good to work locally as well. Will implement.
