Issues listing namespace with cronjobs happening on k8s v1.21.4

[hugodopradofernandes]

What steps did you take and what happened: Namespace does not load at all on Octant when it tries to display cronjobs.

What did you expect to happen: Items from workspace to load - cronjobs causing the issue. When displaying only workloads, works fine. When cronjob is part of the view, it fails

Anything else you would like to add: [Miscellaneous information that will assist in solving the issue.] Namespace that Octant could not list

batch/v1beta1 CronJob is deprecated in v1.21+, unavailable in v1.25+; use batch/v1 CronJob

[brunnels]

I can confirm this is still happening with apiVersion: batch/v1 CronJobs using 0.25.0 in windows

[brunnels]

This should be a simple fix. Any chance to get a new release?

[flo-mic]

I'm facing the same issue when browsing a namespace with Cron jobs enabled (e.g. a nextcloud deployment from this chart https://github.com/nextcloud/helm/tree/master/charts/nextcloud). The cron jobs use the "batch/v1" API and the kubernetes version is v1.22.

[haiwu]

I just hit the same issue.

[ITH-Icoserve]

Same issue here, on kubernetes v1.23.3

[wizardofdevops]

same issue

[mpccolorado]

Same issue

[pbebbo]

same issue

[ScottAlbertine]

Same issue, even after changing all cron jobs to be v1 instead of v1beta1

[tihakkar643]

Same issue. Using batch/v1

[Freydal]

I'm pretty sure the following needs to be updated to batchv1. I haven't fully vetted if it isn't going to break anything, but roughly fixed the issue at hand.
