Added ansible role of met-observatiosn-collector though with broken encrypted credentials
Fixed erroneous unicode character
Update API_URL and API_KEY encrypted vars

Note: Used HTTP (not HTTPS) - if HTTPS is available we should use it.
Reorder - make repo dir before credentials file

Otherwise the credentials file has nowhere to live.
Merge pull request #25 from sealevelresearch/met-observations-collector
