Add label to serial nodes

[akalenyu]

Adding a label in order to be able to filter tests decorated with Serial.

Fixes #1483

@onsi Are the failures caused by the PR?

[onsi]

yes - this line:

https://github.com/onsi/ginkgo/blob/master/integration/timeline_test.go#L141

needs to changed to a full timeline [Serial]\n

you should be able to ginkgo -r -p from the root directory and see it all go green. Every now and then an integration spec will flake on a slow machine but they are generally pretty reliable so if you see a failure it’s probably the new code. In this case adding Serial as a label changed the output and we’ll need to update the test.

Added. I couldn't understand who sets the serial decorator on this timeline test though
