Cherry pick of #117792 #117724 on release-1.26.

#117792: kubeadm: Use internal etcd client through an interface
#117724: kubeadm: Make etcd member removal idempotent

For details on the cherry pick process, see the cherry pick requests page.

Note: This should only merge if the cherry-pick for 1.27 (#117948) merges.

If `kubeadm reset` finds no etcd member ID for the peer it removes during the `remove-etcd-member` phase, it continues immediately to other phases, instead of retrying the phase for up to 3 minutes before continuing.

kubeadm: Make etcd member removal idempotent
fd6645f 
If the etcd member is not found, then it has already been removed, and
kubeadm reset should immediately complete the 'remove-etcd-member'
phase. Previously, the phase would complete only once the
exponential-backoff retry expired, up to 3 minutes duration.

This commit also fixes a semantic error in etcd.GetMemberID. Previously,
the function returned 0 if no member was found, but 0 is not a valid
member ID.
