We already handled request bodies. Now we tackle query parameters. Note that we're only handling GET requests currently since these are the APIs where query parameters are most likely to be present. A future change will add a test to verify that all methods handling GET requests have schemas present. This patch might look huge but every one of these schemas is effectively a no-op since they're empty and have 'additionalProperties = True'. This means there are lots of TODOs left in here which would be nice to tackle in a future API microversion.
