• Upgrade fails when .hammer/defaults.yml exists

Hammer configuration failed: Is the admin password correct? (it was stored in /etc/foreman-maintain/foreman-maintain-hammer.yml)Is the server down?
--------------------------------------------------------------------------------
Scenario [preparation steps required to run the next scenarios] failed.

The following steps ended up in failing state:

  [hammer-setup]

Resolve the failed steps and rerun
the command. In case the failures are false positives,
use --whitelist="hammer-setup"

• When we have specified values in .hammer/defaults.yml (via the hammer defaults command) foreman-maintain will fail to authenticate and error on most commands.

# foreman-maintain  health check

Hammer configuration failed: Is the admin password correct? (it was stored in /etc/foreman-maintain/foreman-maintain-hammer.yml)Is the server down?

this makes it look like the password is incorrect or the server is down, when in fact, there may be a setting in ~./.hammer/defauts.yml that is invalid or conflicting with foreman-maintain's usage of hammer.

This results in failed upgrades with difficulty determining why:
