[trengrj]

Allow for http/s proxy settings via config:

java-client/src/main/java/io/weaviate/client/base/http/builder/HttpApacheClientBuilder.java

Lines 12 to 19 in 0ab5c7e

	public static CommonsHttpClientImpl.CloseableHttpClientBuilder build(Config config) {
	RequestConfig requestConfig = RequestConfig.custom()
	.setConnectTimeout(config.getConnectionTimeout() * 1000)
	.setConnectionRequestTimeout(config.getConnectionRequestTimeout() * 1000)
	.setSocketTimeout(config.getSocketTimeout() * 1000).build();
	return HttpClientBuilder.create().setDefaultRequestConfig(requestConfig)::build;
	}
	}

Can use setProxy:

HttpHost proxy = new HttpHost("proxy-host", 8080, "http");
RequestConfig.custom().setProxy(proxy)
