summary:     Implement new job runner super class ClusterJobRunner intended to reduce amount of duplicated code between drmaa, pbs, and lwr job runners (also I guess cli and condor classes seem like they could benefit from this as well). This super class will manage the monitor and worker threads and queues.
I am submitting only changes to the LWR that use this class, but I would encourage the Galaxy team to refactor the drmaa and pbs runners to use this class as well (or I would be happy to make these changes if given access or a promise the changes will be accepted quickly).
A variant of the drmaa runner that has been refactored to use this class can be found here: https://bitbucket.org/jmchilton/galaxy-central-lwr-enhancement-1/src/tip/lib... from the now defunct pull request 80.

summary:     Refactor the LWRJobRunner to be a ClusterJobRunner and implement a recover method for this runner, the upshot of this is that LWR jobs can now survive Galaxy restarts. Downside is that jobs are no longer queued on Galaxy server, so LWR server should be updated (to changeset 5213f6d or newer) to queue jobs on the remote server. This is not manidatory however, this will still work it is just more jobs may run simultaneously than is desired.

summary:     Rework job_id handling in LWR runner allowing remote LWR server to assign a job_id during setup, save this will serve as the job's external id. This change allows multiple Galaxy instances to submit jobs to the same LWR backend server and will prove useful when implementing additional backends (pbs/drmaa/etc...) for the LWR server.
