feat(@angular/cli): display app index or name in process title when s…

Closes #6888

This sets process title to ng - app <index> when used with --app 0
or to ng - <app-name> when used with --app appName

Had tests like

import { killAllProcesses } from '../../../utils/process';
import { ngServe } from '../../../utils/project';

export default function () {
  return Promise.resolve()
    .then(() => ngServe('--app', '0'))
    .then(() => {
      if (!process.title.match(/ng - app 0/)) {
        throw new Error('Process title does not match expected value.');
      }
    })
    .then(() => killAllProcesses(), (err) => { killAllProcesses(); throw err; });
}

but removed them because they were failing on Travis CI and appVeyor. The process title was set to node in those environments.

This and another test for checking app by name (not index) were working locally on Win10, cygwin, any idea how we can make them work on CI environments ? @filipesilva @Brocco

Besides that, it works as described in original issue. Also, for consideration, the original ng process name is not tested either.

@hansl can you take a look please?

This seems to have gone stale, do we still need this change?
Sorry @tomastrajan

Hi @alexeagle ! As you might noticed this is a rather very old PR from December 2017, it was meant to display app name (instead of app index) in the toolbar of the console when running specific app in a multi app scenario. Angular CLI experience quite some evolution since that time so I don't really know if this is still applicable. Might have a look and try to update it if you think it is worth it :)
