* ui: Add a way to reliably figure out where the UI is running
The main javascript that we use is at </where/the/ui/is>/ui/assets/consul-ui.js
This uses this fact to provide and base path 'environment' variable to
be used within the app. This is also overwritable via various methods
(testing/development) if we ever need to do that.
* Remove BASE_API_URL, the logic here isn't exactly correct
Right now the API always _has_ to be at http://domain/v1/ i.e. the root
of your domain /v1. If the URL of the ui is set differently to
http://root.com/somewhere/else/ui/ then the API is still at http://root.com/v1
There is definitely a plan to add this env var back in at some stage so
we can potentially allow this to be configured in other ways, but there
isn't a need to do it just yet so we don't need to worry about _how_ to do
this right now.
This commit includes 2 things:
1. Sometimes (seemingly due to client caching), performance entries
aren't available, even for the currently executing script. This waits
until the first retrieval of 'CONSUL_HTTP_PROTOCOL' before using the
performance entries to decide this. This means that the entries aren't
inspected until ember has initialized, which means that the entries are
always available.
2. getCurrentResource/getResourceFor could potentially return undefined
if the correct entry could not be found. This adds a default {} return
value if the resource cannot be found. This means that if for whatever
reason the correct resource cannot be found at least we don't fail with
an error and just drop back to HTTP/1 functionality.
