Foreman Maintain

From the Bugzilla
~_~~~~~~~~~~~~~~
Description of problem:
foreman-maintain lower cases the uppercase characters while saving hammer credentials

Version-Release number of selected component (if applicable):
rubygem-foreman_maintain-0.0.11-1.el7sat.noarch

How reproducible:
Always

Steps to Reproduce:
1. Say Satellite hammer password is CHANGEME!@#$%
2. Install rubygem-foreman_maintain
3. Run any foreman-maintain command: Example:

1. foreman-maintain upgrade check --target-version 6.3.z

Running preparation steps required to run the next scenarios ================================================================================
Setup hammer:
Hammer username [admin]:
Hammer password:
Invalid credentials

Actual results:
The foreman-maintain fails with invalid credentials even though you enter the right password

/etc/foreman-maintain/foreman-maintain-hammer.yml saves the password as `changeme!@#$%`

All the upper case characters are lowercased. As far as I checked, the special characters look fine.

Expected results:
credentials should be saved properly

Additional info:
Changing the credentials in /etc/foreman-maintain/foreman-maintain-hammer.yml works fine.
