report exactly which jobs will be deleted.

Using the glob parameters option to delete jobs, like so..
jenkins-jobs --conf jenkins_jobs.ini delete --path defs/cmd-002.yaml *bar*

JJB would report the following:

  INFO:root:Deleting jobs in [*bar*]

This change provides better info on exactly which jobs will get deleted.
Now the log will report:

  INFO:jenkins_jobs.builder:Removing jenkins jobs: bar001, bar002
