What type of PR is this?

/kind bug

What this PR does / why we need it:

Fix for #7668. In commit c382519 the binding of the leader election flags was moved under kube_flag.InitFlags() which is responsible for parsing the flags. This resulted in the leader election flags not being known anymore when starting the cluster-autoscaler. Trying to pass any of the --leader-elect flags would fail and crash it: unknown flag: --leader-elect.

By moving the binding of the flag above parsing (kube_flag.InitFlags()) like it used to be, the flags are available again.

Which issue(s) this PR fixes:

Fixes #7668

Special notes for your reviewer:

Does this PR introduce a user-facing change?

Bugfix: --leader-elect flags can be specified again. Removed --lease-resource-name flag that was redundant with --leader-elect-resource-name.

Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

Hi @idebeijer. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
