[JAVA/okhttp-json] some errors in api.mustache template in relation to localVariablePrefix

[UnHumbleBen]

Description

There are a few unresolved variables in the api.mustache template:

callback should NOT have prefix since it is not a local variable:

swagger-codegen/modules/swagger-codegen/src/main/resources/Java/libraries/okhttp-gson/api.mustache

Lines 222 to 265 in bdb4edd

	/**
	* {{summary}} (asynchronously)
	* {{notes}}{{#allParams}}
	* @param {{paramName}} {{description}}{{#required}} (required){{/required}}{{^required}} (optional{{#defaultValue}}, default to {{{.}}}{{/defaultValue}}){{/required}}{{/allParams}}
	* @param callback The callback to be executed when the API call finishes
	* @return The request call

	callback.onDownloadProgress(bytesRead, contentLength, done);
	}
	};
	progressRequestListener = new ProgressRequestBody.ProgressRequestListener() {
	@Override

	return {{localVariablePrefix}}call;
	}

apiClient is missing prefix here:

swagger-codegen/modules/swagger-codegen/src/main/resources/Java/libraries/okhttp-gson/api.mustache

Line 117 in bdb4edd

apiClient.getHttpClient().networkInterceptors().add(new com.squareup.okhttp.Interceptor() {

Suggest a fix/enhancement

I fixed the template locally. Will make a PR.
