Close ResponseBody

[sowieso-fruehling]

I'm using your snowplow-java-tracker:0.8.2 and I have a following issue occuring:

WARN [OkHttp ConnectionPool][][] c.s.o.OkHttpClient 305: A connection to <my_url> was leaked. Did you forget to close a response body?

After debugging it I saw that your code is calling AbstractHttpClientAdapter.post(SelfDescribingJson payload) which calls OkHttpClientAdapter.doPost(String url, String payload) which calls com.squareup.okhttp.Call.execute() and documentation for this method says:

The caller may read the response body with the response's

• {@link Response#body} method. To facilitate connection recycling, callers
• should always {@link ResponseBody#close() close the response body}.

and you're not doing it in your library. OkHttpClientAdapter.doPost(String url, String payload) returns response code and never closes response body. Reading other resources it seems that the warning I get is exactly the consequence of not closing it

Did I get something wrong here, or it's a bug?

It does look like an oversight, feel free to open a pull request 👍

I made a pull request but not all of your CI jobs are passing. java 8 one passes but java 7 ones are failing, and it's not related to my changes
