[COM-34] Management of RDS Instance via System Initiative

[stack72]

As part of the work to finish #2647, we need to be able to create databases with System Initiative.

We need to be able to create a postgres server with the following options:

• Postgres 14.7 version
• Multi DB Instance (not a cluster)
• Pass an instance identifier
• Pass a username and password (password will be secret in a future version)
• Pass an instance type
• Pass storage type, size and IOPS
• Pass a DB Subnet Group Name
• Pass a DB Parameter Group Name
• Enable public access / not
• Set up a maintenance window
• Set up Backup Options
• Pass a list of Security Group IDs to the instance
• Enable Deletion Protection
• BONUS: Be able to trigger a snapshot from an Action

We also need to be able to create a DB Parameter Group -https://awscli.amazonaws.com/v2/documentation/api/latest/&path=reference/rds/create-db-parameter-group.html. This DB Parameter Group needs to have an Output socket of DB Parameter Group Name so that it can be passed to the DB Instance
