Ansible 2.14.3 introduced a change that broke the method used for
restarting MariaDB and RabbitMQ serially [1][2]. In
I57425680a4cdbf0daeb9b2cc35920f1b933aa4a8 we limited to 2.14.2 to work
around this. Ansible upstream claim this behaviour was unintentional,
and will not fix it.
This change moves to a different approach where we use separate plays
with a 'serial' keyword to execute the restart.
This change also removes the restriction on the maximum supported
version of 2.14.2 on ansible-core - any 2.14 release is now supported.
