------------------------------------------------------------------
[~shining] There are a few comments on your PR. Can you please have a look and
address them? We are planning to make Avatica 1.14.0 available for voting soon,
and I'd like to include this PR if possible.

> When use avatica connect Phoenix QueryServer, I create an AvaticaConnection:
> {code:java}
> Connection conntion = DriverManage.getConnection(url);
> connection.setAutoCommit(true);

> Avatica keep PhoenixConnection alive in the Cache, which will be expired
