k8s:build fails to build image when image tag contains +

[rohanKanojia]

Describe the bug

originally posted by @cimnine in #1859

If we configure Kubernetes Maven Plugin to use image name like this:

<jkube.generator.name>%a:4.3.3-SNAPSHOT+st1666023054591-b24-7ca68455</jkube.generator.name>

k8s:build fails with the following error saying image name is invalid:

The given version is a valid SemVer version, however, it's not a valid image tag name. We should replace + character with some other character to handle this scenario.

Eclipse JKube version

1.13.1

Component

Kubernetes Maven Plugin

Apache Maven version

other (please specify in additional context)

None

Steps to reproduce

Change image name generated by jkube to %a:4.3.3-SNAPSHOT+st1666023054591-b24-7ca68455 using property jkube.generator.name

Expected behavior

k8s:build should handle + tag by replacing it with some other docker compatible token

Runtime
