run bamboo build agent and datacube deployment as appropriate user on devdatacube

[chrisbarber]

Also, the bamboo agent should be run as a service so it comes back up on reboot, etc.

The first part of this is done; bamboo agent is being run as mongrel.

Remaining things:

1. ansible playbook should be refactored so that tasks requiring root privileges can be excluded via a tag, allowing automated deployments to skip root tasks. Currently I have mongrel ssh-agent loading root@devdatacube's ssh key as a workaround. This should be removed.
2. Bamboo agent should be run automatically on startup as mentioned in the description.

Current steps to run bamboo agent after a restart, until above are resolved:

1. ssh to devdatacube
2. su to mongrel
3. cd ~
4. screen -S bamboo
5. `eval "$(ssh-agent -s)"
6. ssh-add ~/root_keys/id_rsa
7. java -jar atlassian-bamboo-agent-installer-5.14.1.jar http://bamboo.corp.alleninstitute.org/agentServer/
8. detach from screen, logout
