Add ability to specify dependent jobs in trigger

This patch allows to configure dependent jobs for trigger, which
is especially usefull for case when multiple jobs are triggered
from gerrit.

There is pillar example:
  job:
    myjob:
      trigger:
        gerrit:
          dependency_job_names:
            - job1

* Fix test pillars to use java 11 as 10 is no longer awailable for
download
