Bug 16699: Add borrowernumberQueryParam for reusability

The borrowernumber as a query parameter should be defined in parameters.json
in order to allow its reusability.

To test:
1. Apply patch
2. Run minifySwagger.pl
3. Validate swagger.min.json in online.swagger.io/validator/debug?url=url_to+
   _your_swagger_min_json or your local swagger-api/validator-badge validator
4. Observe that validation passes

We have been using the Swagger2.0-driven REST API on Mojolicious for 1 year now
in production and I am certain we have a pretty good idea on how to work with
the limitations of Swagger2.0
We participated in the development of the Mojolicious::Plugin::Swagger and know
it well. We have made an extension to the plugin to provide full CORS support
and have been building all our in-house features on the new REST API.
