Foreman Maintain

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1628926

This command does not work on C locale (which is also known as simple or default locale, no translations, used for scripting as a prevention of locale issues):

1. LC_ALL=C foreman-maintain service status
   /usr/share/gems/gems/foreman_maintain-0.2.7/definitions/features/mongo.rb:181:in `===': invalid byte sequence in US-ASCII (ArgumentError)

The problem is pulp config file (/etc/pulp/server.conf) contains UTF-8 characters and this causes issues when the default encoding is US_ASCII:

1. ca_path: The ca_certs file contains a set of concatenated “certification authority”
