Allow API owner to select one from several configured proxies

[bajiat]

If there is more than one API Umbrella proxy defined for deployment, allow the API owner to select one of them in the Proxy backend settings.

Definition of done

• If there is more than one API Umbrella defined, owner can select any of the defined proxies, when adding or editing proxy backend settings.
• If there is only one API Umbrella defined, a simple solution is available for defaulting to the only API Umbrella.
• Proxy base path will come from selected proxy.
• Show an alert to owner, if switching between proxies: "This change will potentially break API calls from applications, if API users are not warned about the change."

Open issues: If owner changes the proxy, do we need to delete the proxy backend from the original proxy? Users will have a broken link, is it our responsibility to notify or is it owner's responsibility to warn the users?

Wireframes

• In API profile Proxy tab, a dropmenu would appear depending on if there are more than 1 proxy available for selection.
  Open question: in case of only one proxy avialable, should we show the name as hard coded?
  

• On selecting a specific proxy, associated fields for that proxy would be populated. In the case for only one available proxy, the fields can appear instantly Proxy tab is selected for viewing:

• When API owner tries to switch from one proxy to another, the following alert window should appear:

Open Question: Need to consider the scenario when owner wishes to switch from one proxy to another...Alert message?

@marla-singer Could you take this task?

[marla-singer]

@bajiat yes, take it.

[bajiat]

@marla-singer Great! Can you please estimate the task in days?

[marla-singer]

@bajiat Well, I'm not sure, maybe 2-3 days.

Show an alert to owner, if switching between proxies: "This change will potentially break API calls from applications, if API users are not warned about the change."

Is it essential to notice user in process switching? Can it be simply static sentence like:
"Be careful: Changing proxy will potentially break API calls from applications, if API users are not warned about the change."

@marla-singer Are you talking about the owner seeing the progress that the proxy has been switched to another one? I think there a simple feedback dialogue would be good. When the process is done an confirmation dialogue as well. However, I think API users should be notified about the change because they would see a broken link in the API profile page
