Bug 1032802

Description of problem:

The WebUI does not currently allow users to perform repo discovery using file URLs.

Version-Release number of selected component (if applicable):
katello-1.4.6-61.el6sat.noarch

How reproducible:
always

Steps to Reproduce:
1. go to Content->Repositories->Products
2. click Repo Discovery
3. enter a file resource URL (e.g. file:///var/www/html/repos)

Actual results:
The Discover button is disabled

Expected results:
The Discover button is enabled

Additional info:

As a workaround, it is possible to accomplish repo discovery using the CLI.

Pre-requisite, the product used in the CLI should exist prior to discovery:

For example:

$ katello --username admin --password [password] shell

katello> repo discover --org ACME_Corporation --name my_repo_prefix --url=file:///var/www/repos --product zoo
