Are we assuming that we will never want to access another database with this method?  DB clients should have the ability to select the DB to use at connection time.  Even if we move this to `mysql` cookbook (which I agree with), it should have the option to select a DB.  Otherwise, we should change the comment to:
```ruby
# Connects to mysql as 'root' user to no database, performs a mysql query, and returns the output of the query.
```
