Basic deployment scripts

Basic deployment scripts, written in bash.
Should work on all host machines, and Debian/Ubuntu remote deployment targets.
Tested and works on Ubuntu 12.04.1 LTS.
The promotion part is still a stub since we did not decide on how to host our codes on the targets.
Deployments of configurations should also be worked on later.
I think it is wrong in our coding convention.
change to
```python
from yaml import load
```
