Fix parameter name in database configuration for MySQL2

[voicewise]

The configuration parameters required by mysql2 are "name" and "password". The parameter "username" rises a warning.

What does it do?

I changed the name of mysql2 configuration from "username" to "user" since the first one rises a warning.

Why is it needed?

It provides updated information about mysq2 configuration
