[scylla-node]: upgrade: avoid restarting the service when the version that is about to be installed is already installed

[vladzcloudius]

HEAD: dc53597

Description

In the "upgrade" mode the Role is going to drain, stop, start the scylla service even if the version that is requested to be installed is already installed.

This is obviously a waste and we should consider improving it.

For that we need to resolve the full scylla version and compare it to the already installed one.
For example, if scylla_version: 2024.1.11 + upgrade_version: true are given, then we need to resolve the full version first.
It's going to be 2024.1.11-0.20240928.13ee6268a233-1.
When, if the corresponding package is already installed the Role should skip the draining and the rest for the corresponding node.
