Zswag

What's Changed

* 113: We now support specifying multiple OpenAPI servers, and give the user the choice to select one in the OAClient constructor in Python and C++.
* 114: We now allow parameters which do not contain `x-zserio-request-part`. A warning is issued if such parameters are not optional.
* 116: The http-settings YAML format is improved: It can now also read a top-level `http-settings` key, so other applications can use the same file. The `url` field is simplified. Instead of `url`, a user may now define `scope` which uses simple wildcards instead of regular expressions.
* 92: zswag clients now support gzip HTTP compression.
