app/regex: add RegEx test application

Following the new RegEx class.
There is a need to create a dedicated test application in order to
validate this class and PMD.

Unlike net device this application loads data from a file.

This commit introduces the new RegEx test app.

The basic app flow:
1. Configure the RegEx device to use one queue, and set the rule
   database, using precompiled file.
2. Allocate mbufs based on the requested number of jobs, each job will
i  get one mbuf.
3. Enqueue as much as possible jobs.
4. Dequeue jobs.
5. if the number of dequeue jobs < requested number of jobs job to step
