GitHub Issue:

• Fixes Playbook fails during geerlingguy.mysql while setting up replication. (need to update role) #280

• Other Relevant Links (Google Groups discussion, related pull requests,
  Release pull requests, etc.)

What does this Pull Request do?

• Replaces the 'include' directive that was removed in ansible 2.16 with 'import' or 'include_tasks'. see '"include" is deprecated, use include_tasks/import_tasks instead.' deprecation warning is without link to place explaining how to deal with it ansible/ansible#76684
• Updates the geerlingguy.mysql role because of replication error
• Adds drush path as a variable to the vagrant inventory.
• Changes the format of the permissions string to that Ubuntu likes it.

What's new?

• Does this change require documentation to be updated? no
• Does this change add any new dependencies? no

  (i.e. Regeneration activity, etc.)? no
• Could this change impact execution of existing code? no

How should this be tested?

Try to spin up a playbook (local or remote). You will encounter:

• include is deprecated
• mysql replication fails
• drush is not found.

With this PR, it should run smoothly.

Can you test on Red Hat? (Can we support Red Hat? )

Still trying to replicate this issue: #279

Tried this on my local that can still run Vagrant and it works.

One odd thing is Vagrant freezes when trying to ssh in for the first time but running vagrant provision after that works so Ansible is not the issue.
