Description Abhinav Dahiya 2020-04-28 16:03:15 UTC

Description of problem:

previously all the errors were context Deadline exceeded, with this change the error returned is the last tracked error.

This is useful as the user has more information about what the failure could be.

For example, BZ https://bugzilla.redhat.com/show_bug.cgi?id=1810318#c8
the `.openshift_install.log` had the following debug log.
```
time="2020-03-04T21:08:13Z" level=debug msg="Still waiting for the Kubernetes API: Get https://api.openshift10.az.test-am-cloudpak.io:6443/version?timeout=32s: dial tcp: lookup api.openshift10.az.test-am-cloudpak.io on 127.0.0.53:53: no such host"
```
but the error returned to the use was
```
FATAL Bootstrap failed to complete: waiting for Kubernetes API: context deadline exceeded
```

returning the last tracked error would help users as they don't have to look into log file for most errors.

Version-Release number of the following components:
rpm -q openshift-ansible
rpm -q ansible
ansible --version

How reproducible:

Steps to Reproduce:

The issue has been verified on nightly build: 4.5.0-0.nightly-2020-05-07-033157.
During cluster installation, after lb server is powered on, shutdown it and let installation failed.
The console output print the last error instead of "context deadline exceeded"

On previous load, we can see "context deadline exceeded" when haproxy service is not started on lb server.
