Added jobSpec to create test job in e2e

[k82cn]

DESCRIPTION: -- symptom of the problem a customer would see

Currently, we use createJob with several parameters to create test jobs. There're two major issues:

1. if added one more field for Job to set, we need to update all related test cases
2. we can not create multiple jobs with same podgroup

It's better to introduce a test struct, named jobSpec, to cover that; for example

type jobSpec struct {
	name       string
	podgroup   string
	scheduler  string
	min, rep   int32
	img        string
	hostport   int32
	req        v1.ResourceList
	affinity   *v1.Affinity
	labels     map[string]string
	containers []v1.Container
}

func createJobs(
	context *context,
	jobs []jobSpec,
) ([]*batchv1.Job, []*PodGroup) {
    ...
}
