README:

 Enable these tests by passing '-local' to the go test command

 Only database supported for now is MySQL. Postgres could be easily extended if needed.

 It is expected that the data folder of CGRateS exists at path /usr/share/cgrates/data.

 Prior running the tests, create database and users by running:
  mysql -pyourrootpwd < /usr/share/cgrates/data/storage/mysql/create_db_with_users.sql
