[Sahara] Job Exeuctions page should be Jobs

[Ken Chen]

The Jobs page has a title "Job Executions", which is confusing, for job_execution was already deprecated in Sahara. Need to rename to "Jobs".

    Rename Job Executions to Jobs in Jobs page

    We rename the title of Jobs page into "Jobs" instead of old "Job
    Executions" to avoid user confusion.
