Supporting RHEL 6 systems

[mhamrah]

My first attempt was to follow the Mesosphere instructions displayed in #4 but that approach has some shortcomings. First it requires CDH repo which installs a lot of unnecessary dependencies, and the file layout and configuration override has some shortcomings when used with ansible.

Instead it's much easier to use the download-src approach and configure the init files by hand, which is what this repo is doing already. I just had to tweak some settings:

• I had to change the upstart script because setuid is not available in the upstart version on Centos.
• I modified how the zoo.cfg server list was being built to make it easy to use group variables in an inventory for declaring hosts.

You can have:

[mesos_masters]
hostname1 zookeeper_id=1
hostname2 zookeeper_id=2

and in your role have:

 - { role: './librarian_roles/ansible-zookeeper', zookeeper_hosts: "{{ groups.mesos_masters}}", tags:['zookeeper'] }

No need to build/maintain a separate array.

Need to test on Ubuntu, but I think the su thing will work.

I also pulled zookeeper support from AnsibleShipyard/ansible-mesos#16 but haven't pushed.

This is ready-for-review, but could use some enhancements in certain areas.

• Ubuntu systems uses the debian package (too many issues with running from source)
• RHEL systems download zip from apache and configures upstart manually
• Not sure how the Travis CI is configured or why its failing.

I added the travis yml and tests from Marathon. so this should be good to merge.
