Create mocks from intercepted requests

[waldekmastykarz]

Create a new summary plugin that creates mocks from the intercepted requests. This will allow users to create mocks based on their data.

After generating the mocks, the plugin sorts them descending by URL length to put the most specific URLs upfront and more generic URLs in the back. This will allow users to replace IDs with wildcards to generalize their mocks and ensure that they will execute in the correct order.
