[vagrant] forwarded http port to 8080
[kameleon] kept oar sources inside the appliance
[tests] Supported Vagrant appliance (do not hardcoding username)
[job_resource_manager] add fstrim when purging directories
[job_resource_manager] temporary disable net_cls cgroup

The net_cls cgroup feature seems to not be enabled in the Debian kernel 3.13.
Moreover we have never used this feature so we disable it.
[job_resource_manager] enable memory cgroup by default
[tmp_job_uid] remove temporary job uid feature

Remove the temporary job uid feature which was enabled by
JOB_RESOURCE_MANAGER_JOB_UID_TYPE in oar.conf.
It creates dynamically a user for each job.
It was never used and it makes the code more complex.
[doc] intel mpi usecase
[deploy] do not run ping checker at the end of a deploy job

Bug #17128: when ACTIVATE_PINGCHECKER_AT_JOB_END is on and the job is of deploy
type then we don't launch pingchecker (the node is typically rebooting).
[oarexec] bug when epilogue error + job delete

Bug fix: when a job was deleted and the epilogue script timed out (or exit code
!= 0) then the job was in the state Terminated instead of Error.
[job_resource_manager] cleanup the code
[judas] disable sending log by emails on oar_errors

This could generate too much mails (has already happened and the mail server
has received more than 100000 mails).

[bipbip] fix postgres error logs

Fix bad DB disconnect that generates the postgres log:

   LOG:  could not receive data from client: Connection reset by peer
   LOG:  unexpected EOF on client connection
[noop] implement noop job type

If a job is of the type 'noop' then nothing is done except reserving the
resources during its walltime.

This kind of job terminates at the end of its walltime or when it is deleted
(oardel).

Also, fix oarsub exit without right DB disconnection.
