Rely on galaxy role to deploy postgresql DB

[alxgomz]

Task description

ℹ️ This task requires to be familiar with Alfresco and understand the architecture of its platform.

Currently playbook deploys a very basic PostgreSQL instance for the sole sake of convenience. There are other (and probably better) playbooks on galaxy to deploy PostgreSQL. We would like to rely on using 3rd party roles for deploying 3rd party components (as it's been done lately for the elasticsearch role)

Target OS

Ideally all supported OS (as in supported by the playbook)

Acceptance Criteria

• role needs to be maintained
• role must not be copied and edited
• role can be wrapped
• Role inclusion must not change the inventory structure (no new group or subgroup)
• Version of deployed ActiveMQ can be set so it matches each ACS supported matrix
