[warjiang]

What type of PR is this?
/kind feature

What this PR does / why we need it:
upgrade bitnami/common dependency in karmada chart
Which issue(s) this PR fixes:
no related issue, but as part of another pr #4785
in this pr, we combine all image secrets together, this is reduce similar code like :

{{/*
Return the proper Docker Image Registry Secret Names
*/}}
{{- define "karmada.agent.imagePullSecrets" -}}
{{ include "common.images.pullSecrets" (dict "images" (list .Values.agent.image) "global" .Values.global) }}
{{- end -}}

but this is introduce another problem, bitnami/common@1.x.x will not handle duplicate secret names in chart, after upgrade it to bitnami/common@2.x.x, it will use uniq to remove duplicate secret names in chart.
