script to check for dependencies and to start all services about qiita

[adamrp]

Can we close this?

[antgonza]

I still think we need something that does this. Something like qiita start,
qiita stop, qiita check-installation

[adamrp]

Okay, can you tackle this? Should just be:

• start redis
• start postgres
• start ipython clusters
• qiita_env make_env environments (test, production; probably won't be making the "demo" environment in the release version)
• start webserver.py
