Description of problem:

Users cannot install single-node-openshift if the hostname contains the word etcd

Version-Release number of selected component (if applicable):

Probably since 4.8

How reproducible:

100%

Steps to Reproduce:

1. Install SNO with either Assisted or BIP
2. Make sure node hostname is etcd-1 (e.g. via DHCP hostname)

Actual results:

Bootstrap phase never ends

Expected results:

Bootstrap phase should complete successfully

Additional info:

This code is the likely culprit - it uses a naive way to check if etcd is running, accidentally capturing the node name (which contains etcd) in the crictl output as "evidence" that etcd is still running, so it never completes.
