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

[rosiel]

The Geerlingguy playbook for sql fails:

TASK [geerlingguy.mysql : Check master replication status.] ********************
fatal: [default -> {{ mysql_replication_master }}]: FAILED! => {"msg": "Empty hostname produced from delegate_to: \"{{ mysql_replication_master }}\""}

I've tried adding the following to group_vars/database.yml:

mysql_replication_role: ''
mysql_replication_master: ''
mysql_replication_user: {}

but to no avail.

I was able to get it working with this change:
geerlingguy/ansible-role-mysql@b04a0ca

which is part of the latest tag, 4.3.4.

We should update requirements.yml to include the newest Geerlingguy Mysql role.
