Security context of supportbundle-agent deamonset is not exposed

[zhulinfeng1212]

When consuming this project and extent the sript to collect more nodes information, some commandline (eg iptable) needs higher privilege, while the securityContext is hardcoded in go code see
https://github.com/rancher/support-bundle-kit/blob/master/pkg/manager/agent.go#L85
Is it possible to expose Security context of supportbundle-agent deamonset as a parameter ?
