BUG: Long namespace/service names break up thing in many places

[Hi-Fi]

There has been quite many times, when Kolga's way of generating names has hit severely to deployment, one e.g. https://github.com/City-of-Helsinki/yjdh/runs/4837858868?check_suite_focus=true:

Error: rendered manifests contain a resource that already exists. Unable to continue with install: NetworkPolicy "hl-365-automated-message-when-application-reopened-y-net-policy" in namespace "yjdh-hl-365-automated-message-when-application-reopened-638" exists and cannot be imported into the current release: invalid ownership metadata; annotation validation error: key "meta.helm.sh/release-name" must equal "hl-365-automated-message-when--review-yjdh-bf-bknd": current value is "hl-365-automated-message-when--review-yjdh-bf-appl"

Max length of all possible generated name parts should be determined, and e.g. hashed to be short enough. Now it seems that name lenght comes back quite often.

E.g. https://github.com/City-of-Helsinki/review-services-action/blob/main/src/utils.ts#L7-L20 has of course easier job as there's only one name to generate, but in Kolga's case it would be enough to take the "worst" case. Usually namespace tells the deployment/app, so pod doesn't necessarily have to repeat that.
