Description of problem:
Foreman-installer - typo in the message 

Version-Release number of selected component (if applicable):
# rpm -qa foreman
foreman-1.11.0.9-1.el7sat.noarch


How reproducible:


Steps to Reproduce:
1) Set your hostname to start with a capital letter (use the sethostname command, or hostname, or edit /etc/sysconfig/network
# hostname Dell-pem610-01.rhts.eng.bos.redhat.com

2) run facter and check that the fqdn shows the capital letter
# hostname
Dell-pem610-01.rhts.eng.bos.redhat.com

# hostname -f
Dell-pem610-01.rhts.eng.bos.redhat.com



3) run the installer, 
# foreman-installer --scenario katello
The hostname contains a a capital letter.

This is not supported. Please modify the hostname to be all lowercase. If needed, change the hostname permanently via 'hostname' command and editing 
appropriate configuration file.
(e.g. on Red Hat systems /etc/sysconfig/network).

If 'hostname -f' still returns unexpected result, check /etc/hosts and put
hostname entry in the correct order, for example:
 
  1.2.3.4 full.hostname.com full

 
Fully qualified hostname must be the first entry on the line
