removed outdated okhttp lib, and updated java native library changes

[rlogasundaram]

Changes made as per the github-api release version recommended:
https://github.com/hub4j/github-api/releases/tag/github-api-1.300

The third party API "okhttp-urlconnection" was outdated. Need to remove the library from the github-api-plugin

Pom.xml

• Removed the deprecated okhttp-urlconnection dependency

SmokeTest.java

• Removed the deprecated classes used in the connectFunctions() method - "HttpConnector", "OkUrlFactory", "OkHttpConnector"
• Replaced the HttpConnector with GitHubConnector
• Removed the mock test for OkHttpConnector which is deprecated.
• Creating an object for OkHttpClient and passed as param to the OkHttpGitHubConnector rather than passing param as (new OkHttpClient() ).
• Able to compile the code after making the changes with the below command as guided in the release version of github plugin

mvn -D enable-ci clean install site

Testing Done:

• By compiling the code and build success. Since, SmokeTest.java is the test file which got affected.
