ng e2e does not respect host setting in angular.json

[krotscheck]

🐞 Bug report

Command (mark with an x)

- [ x ] serve
- [ x ] e2e

Is this a regression?

I don't know.

Description

When executing ng e2e, the host parameter in the serve block is ignored.

🔬 Minimal Reproduction

$ ng init yourapp
$ nano angular.json  # add "host": "localhost.local" to serve configuration 
$ sudo sh -c 'echo "127.0.0.1   localhost.local" >> /etc/hosts'
$ ng serve
** Angular Live Development Server is listening on localhost.local:4200, ...

$ ng e2e
** Angular Live Development Server is listening on localhost:4200, ...

angular.json serve block should be:

        "serve": {
          "builder": "@angular-devkit/build-angular:dev-server",
          "options": {
            "browserTarget": "yourapp:build",
            "host": "localhost.local"
          },
          "configurations": {
            "production": {
              "browserTarget": "yourapp:build:production"
            }
          }
        },

Note that passing baseUrl throws an exception.

ng e2e --baseUrl="http://localhost.local:4200"
The 'baseUrl' option cannot be used with 'devServerTarget'.
When present, 'devServerTarget' will be used to automatically setup 'baseUrl' for Protractor.

Hi krotscheck, thanks for reporting this.

There seems to be a bug where the host is not being respected. However, the exception is indeed correct as baseUrl should not be used in conjunction with the devserver.

Well, I was pointing that out more as a "Here's a workaround I tried" bit.
