CLI integration to JVA and code improvement

Currently the JVA has no CLI i've added it using PicoCLI also this commit contains some code improvement which are the following:

• Upgraded JVA to JAVA 11
• Added a new dependency HTTP client for consuming the API : OkHttp which contains async functionnality and would be a good start to consider improve the API consumption.
• Added google guava dependency usefull for improving code quality also it includes good functionnality e.g caching
• Added a feature the CLI using PicoCLI which gives the capability for the user to launch JVA through command line.

The current implementation works with arguments as follows :

Once upon generating the jar with dependency with specifying the Main class, we launch JVA as follows :

java -jar jva.jar -h
this will print the help command the result :
