JENKINS_OPTS environment variable not affect seed-job-agent container.

[guanwei]

when I add JENKINS_OPTS environment variable to Jenkins container:

env:
    - name: JENKINS_OPTS
       value: --prefix=/jenkins

Jenkins run as expect, but seed-job-agent run failed.

NOTE: I installed jenkins-operator in jenkins namespace

$ kubectl -n jenkins get pod

print the seed-job-agent container logs:

$ kubectl -n jenkins logs seed-job-agent-jenkins-79b9656996-bb2xm
