Dejan Mijić ccd8965d6f Use PostgreSQL as primary persistence solution (#175)
* Use normalizer as stream source

Renamed 'writer' service to 'normalizer' and dropped Cassandra
facilities from it. Extracted the common dependencies to 'mainflux'
package for easier sharing. Fixed the API docs and unified environment
variables.
