UI: Fix restoring state for service names containing slashes

[rafikk]

If a service name contains slashes, the web UI shows a blank screen.

Any feedback on this?

@rafikk we generally recommend against using any non-DNS compatible characters in service names. That said, as long as it's allowed in Consul, the UI should support it too. @pearkes any thoughts on this?

[rafikk]

I agree and that's my perspective as well. The point of the UI is to show you state retrieved from Consul. We're successfully registering service names with slashes and utilizing the data via the agent API and consul-template. The only tool giving us trouble is the Consul UI.

as long as it's allowed in Consul, the UI should support it too

Can we merge this change then?

FWIW, the services we're registering are running in Apache Aurora where the convention is that they are named cluster/role/environment/service. Marathon also supports application groups which use hierarchical naming. I expect we are not the only users of Consul who expect this functionality.

@rafikk This should be fine to merge but I think @ryanuber is just waiting on me double checking Ember won't mind. Will do that shortly and give a 👍.

[rafikk]

Sounds good. FYI, I did test this on our Consul cluster and all checked out.

Sounds like this is G2G, so I'm going to merge this in. Thanks, @rafikk!
