Support for newer versions of okhttpclient and logging-interceptor over security vulnerable current versions.

Description

Current codegen cli is using okhttp-2.7.5.jar which has become outdated and also has security vulnerabilities. Is there any way we can upgrade to the newer version of okhttp-3.12.1 jar.

Same is the case with logging-interceptor-2.7.5 jars with logging-interceptor- 3.11.0.

Normally direct version upgrade is not a problem but for these major changes have happened and the package name has also changed.

Command line used for generation

java -jar swagger-codegen-cli-3.0.8.jar generate -i ./test_swagger.yaml --artifact-version Version1-SNAPSHOT --invoker-package com.sample.java.client --api-package com.sample.java.client.api --model-package com.sample.java.client.datamodels -l java -o SampleJava

Start at the codegen CLI dependency declarations and search for references to okhttp-2.7.5 and logging-interceptor-2.7.5. Check the package-name changes while updating them to okhttp 3.12.1 and logging-interceptor 3.11.0, then run the shown Java generation command; done means generation succeeds without the vulnerable versions.
