[release-2.28] Fix: the cluster is upgraded from 2.27 to 2.28 cilium will break (#12324)

* Fix: add cilium remove old resources option

Give users two options: besides skip Cilium, add
`cilium_remove_old_resources`, default is `false`, when set to `true`,
it will remove the content of the old version, but it will cause the
downtime, need to be careful to use.

* Fix: if cilium release exist, the action will set upgrade

`cilium install` is equivalent to `helm install`, it will failed if
cilium relase exist. `cilium version` can know the release exist without
helm binary
