868045: Missed translating string when there are no products for a system
Code review comments lead to discovery of dead code. The import_status and export_status files do not appear tied to any controller and they are only referenced by a route which is also not tied to a controller
820404- Renamed the debug cert button as suggested in the bz
Fixing the reset-oauth script to also do ../config/katello.yml if it exists.
adding thumbslug to headpin's ping function and tests, etc

This commit contains changes to Ping to include Thumbslug in the ping
list. At this time, Thumbslug requires cert authentication for its
ping function to work correctly, so headpin looks for an SSL error
to know whether Thumblug is running or not.

Also contained are spec tests for the Ping model and Ping controller.
All outpoing HTTP requests are stubbed with WebMock, and all OAuth
requests are stubbed at their respective Resource objects.

Included in this commit a new rake take for running
the parallel test with a little more control. It allows for one to run
katello- and headpin-only tests using parallel_test.

for tests, run:

    rake ptest:spec
    # these run with 4 cores, by default
    # tests for headpin vs katello are determined by the 'app_mode' in
    # config/katello.yml

You can also specify a regular expression to single out particular spec
files

run:

    rake ptest:spec['ping'] # spec files with 'ping'
    rake ptest:spec['user|organization'] # runs 'user' and 'organization' spec files
    # runs with one core when you specify a search string though you can
    # override it

    rake "ptest:spec['user|organization', 36]" # run the spec tests on 36 cores. woah!

The way that rspec differentiates between katello and headpin tests is
by placing tags on the test blocks.

To specify a test to run for katello only, add a `:katello => true` tag

    describe "set of katello tests", :katello => true do ... end
    context "set of katello test", :katello => true do ... end
    it "runs a test for katello only", :katello => true do ... end

or `:headpin => true` for headpin-only tests

    describe "set of headpin tests", :headpin => true do ... end
    context "set of headpin test", :headpin => true do ... end
    it "runs a test for headpin only", :headpin => true do ... end

For tests that you want to run on both sides, simply do not
add a tag.
820392 - repository hostname validation

Allow not fully qualified names as a repository URL. Also allow
numbers as first characters. Added some specs for edge cases.
Move all validators to one place

Since validators are not models they should not be in app/models.
All validators are now placed in lib/validators/ and each has its own
definition file.

All validators are in module Validators. When you want to use custom
validation in model you must specify a validator class so it gets loaded
by autoloader. If you use DSL provided by ActiveModel::Validations for
custom validator you'll receive unknown validator error because models
are loaded before lib. That's why we should always use validates_with
when dealing with custom validators.
Code cleanup

To obtain boolean as a result !! is usually used. Also parenthesis in
method definiton for arguments should be used.
Repository feed validation moved to validator

Validation was performed in controllers in API and UI which was not DRY.
This logic is extracted in existing KatelloUrlFormatValidator that was
not used anywhere. This validator uses KatelloUrlHelper which I left
intouched because it can be reused more easily than validator itself.

Since tests did not specify feed because it was not required until now I
had to add feed info wherever fake repository was created.

894480 - remove PyXML dependency

Quote from BZ:
I've opened up a Fedora 19 Feature to remove PyXML due to a combination of it being dead upstream for many years and that when it's installed, the python stdlib overwrites its own xml module with PyXML.  This combination leads to errors because PyXML's code is older and contains bugs that have been fixed in the stdlib.
