Call for jenkins slaves to improve multi operating system support

Hi Ceph,

When a contribution is proposed to Ceph [1], a bot compiles and run tests with it to provide feedback to the developer [2]. When something goes wrong the failure can be repeated on the developer machine [3] for debug. This also helps the reviewer who knows the code compiles and does not break anything that would be detected by "make check".

The bot runs on CentOS 7 and Ubuntu 14.04 only, and problems related to older operating systems (headers, compiler version, etc.) may be detected later, when building packages [4] and after the pull request has been merged in master. This is rare but requires extra attention from the reviewer and needs to be dealt with urgently when it happens.

If you can spare a machine to help expand the operating systems on which tests can run, it would be a great help. The minimum hardware configuration to run a slave is:

*  x86_64 architecture for CentOS 6, Fedora 21, OpenSUSE 13.2, Debian GNU/Linux Jessie, Ubuntu 14.02

  32 GB RAM
  200 GB SSD
  8 core > 2.5Ghz

*  i386 architecture for CentOS 7, CentOS 6, Fedora 21, Debian GNU/Linux Jessie, Ubuntu 14.04, Ubuntu 14.02

  4 GB RAM
  200 GB disk
  2 core

*  armv7, armv8 architecture for Ubuntu 14.04

  4 GB RAM
  200 GB disk
  2 core 

Note that since the make check bot can run in a docker container, x86_64 machines can be used to run any of the operating systems for which a docker file has been prepared [5].

Cheers
