[Functionality] Fetch mocks from recognized URLs

[Idan Tene]

If the document contains direct calls to a URL, offer a "get mock now" link over URL.

Requirements and implementation:

• Statically find URLs via common libraries (i.e. axios, what else?)
• Statically recognize what parameters for the call are static/hard typed, and which are variables.
• Ask user to fill in information for variables.
