HTTP-63 Add caching

[grzegorz8]

Description

Introduce caching similar to the Flink JDBC connector, so long running synchronous Flink jobs can cache content resulting in less API calls.

Resolves #63

I took over this PR: #94 due to author inactivity.

Looks like jacoco report is not generated, logs show:

05:46:48,640 [INFO] --- jacoco-maven-plugin:0.8.7:report (jacoco-report) @ flink-http-connector ---
05:46:48,643 [INFO] Skipping JaCoCo execution due to missing execution data file.

The reason may be related to this added configuration of maven-surefire-plugin

<argLine>--add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED</argLine>

Documentation suggest to add @{argLine} in maven-surefire-plugin if we want to keep this arguments
