[database:*] Support for multiples database

[itsdarrylnorris]

Problem / Motivation

Database dump functionality is hardcore for MySQL. And Drupal 8 support the following databases:

• MySQL 5.5.3/MariaDB 5.5.20/Percona Server 5.5.8 or higher with InnoDB
• PostgreSQL 9.1.2 or higher
• SQLite 3.6.8 or higher

We should add support for these database to add the ability of user backing up their database. There are other types of databases; however, they are not as popular. For now we should try to support those for database dump.

Solution

Add support to the following database.

• MariaDB 5.5.20/Percona Server 5.5.8 or higher with InnoDB
• PostgreSQL 9.1.2 or higher
• SQLite 3.6.8 or higher
