fixes #14293 - display subscription details for hypervisors

[thomasmckay]

• properly sets uuid on subscription_facet
• check both host.hasContent() and host.hasSubscription() for details page
• confirm presence of host.content to prevent js errors

this looks reasonable. What is the easiest way to test it out? Do I need to register w/ virt-who?

I tested this with #5910 but hit a 500 error when attempting to display the page

Here is how I tested:

• install katello nightly from bats, register host to itself with subman
• apply patches
• run the following:

# sudo /usr/share/virt-whom/virt-whom -H hypervisor02.example.com:7BB6F404-F13D-11E5-85F0-39AEDC50F6B3 -e Library                                                     
INFO: Updated host: 8ae8d958-0907-4355-bcc1-506345b542de with guests: [7BB6F404-F13D-11E5-85F0-39AEDC50F6B3]

• attempt to view hypervisor02 from content host list

After doing this, I got a 500 error, it appears that something is trying to call candlepin but not passing in the consumer UUID. I suspect that this error was there before the patches were applied.

Is there a different way to test these PRs?

I cannot reproduce your error:

1. switched to branch
2. ran virt-whom
3. visited content hosts page and was able to select the hypervisor

ACK, my prior test was on a bats machine and I assume the issue was related to me hand-patching.
