Description of problem:
I changed the password of the admin user through the web UI. This change wasn't propagated/duplicated with the hammer authentication file in ~/.hammer/cli.modules.d/foreman.yml, producing the error:

[root@ip-172-31-23-253 ~]# hammer user list
Unable to authenticate user myee
Invalid username or password.

Version-Release number of selected component (if applicable):
6.13.5

How reproducible:
always

Steps to Reproduce:
1. Change admin user password in the web UI.
2. Run a hammer command like "hammer user list".

Actual results:
Hammer command fails.

[root@ip-172-31-23-253 ~]# hammer user list
Unable to authenticate user myee
Invalid username or password.

Expected results:
hammer command should run.

Additional info:
Fix this by changing the password field in ~/.hammer/cli.modules.d/foreman.yml
