Dynamic Content For Elementor

* Bug fix: URLs are now resolved correctly based on https://datatracker.ietf.org/doc/html/rfc3986#section-5.2. #289 * Bug fix: Absolute URLs with a path in a service description will now properly override the base URL. #289 * Bug fix: Parsing a query string with a single PHP array value will now result in an array. #263 * Bug fix: Better normalization of the User-Agent header to prevent duplicate headers. #264. * Bug fix: Added `number` type to service descriptions. * Bug fix: empty parameters are removed from an OAuth signature * Bug fix: Revalidating a cache entry prefers the Last-Modified over the Date header * Bug fix: Fixed "array to string" error when validating a union of types in a service description * Bug fix: Removed code that attempted to determine the size of a stream when data is written to the stream * Bug fix: Not including an `oauth_token` if the value is null in the OauthPlugin. * Bug fix: Now correctly aggregating successful requests and failed requests in CurlMulti when a redirect occurs. * The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections. * Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if the Content-Type can be determined based on the entity body or the path of the request. * Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder. * Added support for a PSR-3 LogAdapter. * Added a `command.after_prepare` event * Added `oauth_callback` parameter to the OauthPlugin * Added the ability to create a custom stream class when using a stream factory * Added a CachingEntityBody decorator * Added support for `additionalParameters` in service descriptions to define how custom parameters are serialized. * The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar. * You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies * POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use POST fields or files (the latter is only used when emulating a form POST in the browser). * Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
