Use suite configuration from opts if it hasnt beed passed by command line

[Andre-H]

Feature request!

As a tester configuring my default test execution
I want to be able to set the "suite" attribute in the Gruntfile.js (optionally)
So that I don't have to worry about this param being passed every time by the command line using --suite

This means I can use Protractors suites feature without worrying that if in my CI or someone else runs the tests without specifying --suite it will run all suites by default...

For instance I can have this in my conf.js (protractor)

        suites: {
        full_regression: [
            './nice-spec.js',
            './interesting-spec.js',
            './boring-spec.js',
            './short-and-sweet-spec.js'
        ],
        smoke_test: [
            './nice-spec.js',
            './short-and-sweet-spec.js'
        ]
        }

And this in my Gruntfile.js

grunt.initConfig({
                protractor : {
            options : {
                keepAlive : true,
                configFile : 'tests/e2e/conf.js',
                                suite: 'full_regression'
            },
            singlerun : {},
            auto : {
                keepAlive : true,
                options : {
                    args : {
                        seleniumPort : 4444
                    }
                }
            }
        }
...
});

When I run grunt it will execute ONLY full_regression suite.

And when I run grunt --suite smoke_test it will execute only smoke_test suite.
