[18.05] Add the canonical URL to grt config

[martenson]

The base url you might be able to devise, but the /grt-admin/ part you probably wouldn't

+0 on this emotionally, but it doesn't hurt so approving. It's really GRT's fault if it provides you a configuration file that doesn't include the correct URL. (And during registration with GRT it provides you the filled out configuration file, so I'm just assuming it's a bug there / or in your copying rather than galaxy.)

@erasche I think I understand but not every interaction with GRT starts at telescope.galaxyproject.org so the users coming from Galaxy should have a ready-to-go config. I think running own GRT is not a very probable scenario.

I was more coming from the thought that when users configure GRT, they'll talk to their GRT server (either from us or another one.) That server providers the grt.yml file for them to use (or at least copy the instance_id / api_key from). Even if that isn't our GRT, their GRT should still be showing them the correct URL to use.

Probably not, but I definitely wanted to make sure people didn't feel like it wasn't an option / wasn't a feature they could take advantage of unless they wanted to send us the data.
