Nexus3: Adapt groovy scripts for newer Nexus3 Releases about helm-charts

[stevehipwell]

No worries @Jasper-Ben, thank you for your help testing the changes! I did offer to donate my chart to Sonatype but they never got back to me and after the work I've done to make it work for others I think I'll keep maintaining it myself (they can always fork it).

FYI @Jasper-Ben REST for cleanup policies.

@Jasper-Ben should this be closed now?

[stevehipwell]

@Jasper-Ben I wasn't aware that the scripts were no longer working but I've been gradually upgrading to the REST API where possible. I've got a branch locally that replaces everything but cleanup, which isn't supported on the API, that I could possibly get released next week (I was holding off for v3.25 to see if cleanup was added). I should probably add a ticket to Nexus3 for a cleanup API.

@stevehipwell delivers again! 😉 Sounds great! Please feel free to point me towards any work that is still left to be done. I already feel guilty for showering you with all the issues popping up 😆

@Jasper-Ben if you want to take a look at PR #56 which is a full refactor of the Nexus 3 chart. The values have changed to hopefully make the chart easier to use and I've documented more of the configuration. If you want to try it out and let me know how you get on I'll attempt to fix obvious bugs, otherwise I'll be waiting until I have more time to test it out myself.

@stevehipwell great! I will give it a try
