Description of problem:

foreman-proxy http port 8000 is enabled while it should be disabled by default

In satellite 6.5 :
------------------

- Port 8000 is enabled and used to get the kickstart files from the satellite server during the provisioning while it should be disabled by default.

# netstat -tulpn | grep 8000
tcp6       0      0 :::8000                 :::*                    LISTEN      16479/ruby 

/etc/foreman-proxy/settings.yml
# http is disabled by default. To enable, uncomment 'http_port' setting
# https is enabled if certificate, CA certificate, and private key are present in locations specifed by
# ssl_certificate, ssl_ca_file, and ssl_private_key correspondingly
# default values for https_port is 8443
:https_port: 9090
:http_port: 8000

If the http port is disabled , the provisioning process fails because the kickstart template can not be imported from the satellite.

Provisioning templates :
Kickstart default PXELinux
APPEND initrd=<%= @initrd %> ks=<%= foreman_url('provision') %> <%= pxe_kernel_options %> <%= ksoptions %>
APPEND initrd=boot/rhel8-baseos-WcW6Pwor7M-initrd.img ks=http://[SATELLITE FQDN]:8000/unattended/provision?token=0baede19-003c-4f21-82dd-145812e42ab0  network ksdevice=bootif ks.device=bootif BOOTIF=00-52-54-00-94-b6-8e kssendmac ks.sendmac inst.ks.sendmac

In satellite 6.4 :
------------------
- Port 8000 is disabled by default and there is no issues with the provisioning process.

  APPEND initrd=boot/RedHat-7.4-x86_64-initrd.img ks=http://[SATELLITE FQDN]/unattended/provision  network ksdevice=bootif ks.device=bootif BOOTIF=00-52-54-00-1c-95-58 kssendmac ks.sendmac inst.ks.sendmac


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

Satellite 6.5 

How reproducible:
100%

Steps to Reproduce:
1. Check ports on /etc/foreman-proxy/settings.yml 

:https_port: 9090
:http_port: 8000


2. Preview the kickstart templates for a provisioned host , all use http://[SATELLITE FQDN]:8000


Actual results:
The http port 8000 is enabled and used by the kickstart templates.

Expected results:

The http port 8000 is disabled by default and not used in foreman_url('provision') as in satellite 6.4
