Support wildcard * in image pattern(image hint)

[panpan0000]

Most helm charts have many components / dependent charts.
just like mariaDB helm chart example :
https://github.com/vmware-tanzu/asset-relocation-tool-for-kubernetes/blob/main/examples/simple-chart/image-hints.yaml

If there're many components/ dependent charts under that helm chart, Then it will very troublesome to write an image hint for each component one by one .
How about adding * to match all components ?

the original image hint:

- "{{ .image.registry }}/{{ .image.repository }}:{{ .image.tag }}"
- "{{ .metrics.image.registry }}/{{ .metrics.image.repository }}:{{ .metrics.image.tag }}"
- "{{ .volumePermissions.image.registry }}/{{ .volumePermissions.image.repository }}:{{ .volumePermissions.image.tag }}"

the proposed image hint will only have 2 lines : one line for 1 level depth pattern , and another for 2 level depth pattern.

- "{{ .image.registry }}/{{ .image.repository }}:{{ .image.tag }}"
- "{{ .*.image.registry }}/{{ .*.image.repository }}:{{ .*.image.tag }}"

If the 3rd level depth, just add .*.*.image.registry

More over , we can use this magical image.hint file to apply to/reuse for many many community helm charts without writing hint file for each helm chart !!!

By this way, I believe this tool will earn thousands of stars :-) Woo~
