Repro steps

Begin with an angular repository with more than one project (two libraries, for instance). Then, attempt to use tslint's --format checkstyle --out <outfile> parameters to output the report to a machine readable format (for jenkins). Documentation for their CLI is here: https://palantir.github.io/tslint/usage/cli/

I have attempted the following:

> ng lint --format checkstyle -o ./checkstyle.xml
Architect commands with multiple targets cannot specify overrides....

> ng lint projectname --format checkstyle --out ./checkstyle.xml
Unknown option: '--out'

# Added format to angular.json >> lint.options.format and lint.options.out
# Format works, adding --out results in 
Schema validation failed with the following errors:
  Data path "" should NOT have additional properties(out).

> ng lint projectname --format checkstyle > ./checkstyle.xml
# Works

Observed behavior

See above.

Desired behavior

It should be possible for the ng lint command to output all of tslint's report formats, in batch mode.

Mention any other details that might be useful (optional)

We're using Jenkins as CI, and the checkstyle reporter to pull in all the generated checkstyle files.

Current workaround for unix-based systems, on the basic folder structure (using projects as the directory).

find projects -mindepth 1 -maxdepth 1 -type d | cut -c 10- | xargs -I % sh -c "yarn --silent lint % --format checkstyle --force > projects/%/checkstyle.xml"

[samherrmann]

@krotscheck, in the new angular.json under the projects field you will see the following:

"lint": {
    "builder": "@angular-devkit/build-angular:tslint",
        "options": {
           ...
         }
     }
}

You should be able to add your format option in there now. See documentation here. I am not sure about the out option though since it's not defined in the options schema.

@samherrmann thanks for sharing the suggestion!
