Add mysql user if not root

[Natkeeran]

Github issue

• CLAW-playbook: Allow for other than root to be drupal_db_user Islandora/documentation#762

Changes

If the user wants to use a drupal user other than root, that user needs to be created. Otherwise, ansible will fail. This PR creates the mysql user and gives permissions for the drupal database for that user.

Testing

• vagrant up with a different drupal_db_user than root: https://github.com/Islandora-Devops/claw-playbook/blob/master/inventory/vagrant/group_vars/webserver/drupal.yml#L20

mysql continue well...

@DigitLib I've seen that recently, too. But I was building for Ubuntu and it would only happen if I attempted to provision twice (due to Fits failing) while still using the root mysql user.

I'll report this on Islandora/documentation#762

I was experiencing the same problem as @DigitLib building on CentOS 7. Attempting to reprovision the vagrant box (i.e. issuing vagrant up --provision after it has provisioned once before) would cause this error. The FITS issue was not related.

@Natkeeran 's PR fixes it.
