Pulp

Description of problem:
We can specify the wrong type of the updated repo, and it's still will be updated.

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

rpm -qa | grep pulp-server

pulp-server-2.5.0-0.14.beta.el6.noarch

How reproducible:
always

Steps to Reproduce:

Since it's not possible to create repos of different types but with the same repo-id, I think it's OK to have a command line as

pulp-admin repo update --repo-id [repod_id]

Otherwise, maybe it's reasonable to include a test for a repo type.
