Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1126731
Description of problem:
I'm bit confused with the validation around the parameter those should contain a valid URL as a value or an IP address as a value.

For example:

if I update "unattended_url" parameter under provisioning tab with utf8 characters then UI throws error "Value must be a valid URI"

Similarly, If I update following params, with any value, UI doesn't raise any error:

- login_delegation_logout_url : accepts all values (-ve value, null values, utf-8, latin-1, html etc)

- signo_url: accepts all values (-ve value, null values, utf-8, latin-1, html etc)

- trusted_puppetmaster_hosts : Since its accepts value in an array, so I can add any value (-ve, null, html) between [].

Also, the parameters whose value can be a IP address should also be validated before accepting the value.

libvirt_default_console_address: accepts all values (-ve value, null values, utf-8, latin-1, html etc)

remote_addr: accepts all values (-ve value, null values, utf-8, latin-1, html etc)

Version-Release number of selected component (if applicable):
sat6 GA snap3

How reproducible:
always

Steps to Reproduce:
1. update all above mentioned parameters under settings menu with some unknown random value.
2.
3.

Actual results:
No validation around above parameters. User can edit all these parameters with any value. A parameter whose value should be only a URL can accept anything. or a param whose value should be an IP address can accept utf8 characters.

Expected results:
Proper validation needs to be placed for parameters. As soon as user input any value, it should be validated by UI and user should get an error message if its a invalid value.
