Bug 34886: Add selenium tests

Tests added to cover different use cases and combinations of circulation rules values for authenticated and unauthenticated users
At the moment, 2 tests are failing, documented on the [DO NOT PUSH] commit.
These 2 failing tests fail for the search results page but pass on the detail page counterpart. Ideally they should match, for consistency sake.
But this may be the use case "details page should be more correct, results page is always an approximation" mentioned by Nick.

More test combinations may be added in the future.
