✨ Add `provision_mapping` ansible role

Decision record

We need to be able to automatically create Reverse Proxy Mapping during the bootstrap of a bubble. This PR introduces a bunch of new Ansible modules to simplify the Ansible logic of said role.

This role can be used by any team that need to provision mappings for their services.

Changes

• ✨ Add ansible module to find the bubble's VIP
• ✨ Add ansible module to create or update the DNS record associated to the mapping
• ✨ Add ansible module to create the certificate associated to the mapping, if it does not exist
• ✨ Add ansible module to create or update the mapping itself
• ✨ Add generic ansible role to create a mapping
• 📝 Add documentation for new provision_mapping ansible role
• 🔖 v0.59.0
