Check if ruby is installed

[lasseebert]

Ruby-common still runs some of the tasks even if the correct ruby version is installed.

The tasks that are run when correct ruby version is already installed:

• apt install prerequisite
• apt install dependencies
• Download ruby source
• Generate rake and gc scripts
• Symlinks

This does not change anything, but takes some amount of time to complete. Should this be avoided with a check on ruby -v?

I'm new to ansible and I'm not sure if this check should be performed by the role or by the playbook that calls the role. Or not at all?

Shouldn't ruby-common check if the desired ruby version is already installed?
