Add oersetter to LaMachine

[proycon]

for Fryske Akademy (depends on #110)

[proycon]

@eduarddrenth This is now implemented v2.4.5 (corresponds to master branch now). I haven't been able to complete a full test though, because of the high memory requirements (at least 32GB!) for the underlying moses servers (which exceeds that of my workstation).

To build a docker container or VM:

• Go to https://proycon.github.io/LaMachine
• Bootstrap a custom LaMachine installation as per the instructions
• Ensure to enable 'oersetter' in the installation manifest
• If choosing a VM, make sure to adapt the memory allocation

For the moment oersetter (and moses) is only supported on Debian/Ubuntu, we can add more flexibility when necessary. LaMachine also allows you to directly provision a remote dedicated server, if needed (without docker/VM overhead).

Thanks, I'm going to test....
