Dropwizard DataSourceFactory on with just DATABASE_URL

[andersem]

Heroku and Dokku only offer a single DATABASE_URL when deploying an application. It would be convenient to create a DataSourceFactory using just this url.

The alternative is to parse the DATABASE_URL and pluck username and password from there, but this is error-prone and makes it hard to use different databases, like h2 in test.

Example database_url:

DATABASE_URL=postgres://postgres:SOME_PASSWORD@172.17.0.1:5432/lolipop

Example database-configuration:

database:
    driverClass: org.postgresql.Driver
    url: ${DATABASE_URL}

dokku/dokku-postgres#22 shows a discussion about this for dokku

That's a reasonable feature request. #1260 should provide the ability to use inlined credentials.
