Migrate circuitsw matrix-verify jobs to freestyle-verify jobs

Migrate circuitsw matrix-verify jobs to freestyle-verify jobs

This patch will:

* Delete the existing {project-name}-verify-{stream} jobs
* Create new jobs {project-name}-verify-{stream}-{maven}-{jdk} jobs
* Remove obsolete cfg file

This work is related to our infra changes mentioned on the mailing list
(see below for link). We'd like to migrate jobs away from using the
matrix type jobs and convert them to freestyle jobs as the matrix system
occassionally causes us build issues especially with larger queue sizes.
