Create guidelines and templates for issues and PRs using github templates

[thammegowda]

Github supports templates to bootstrap Issues and Pull request descriptions with necessary details.

TODO:

• setup .github/ISSUE_TEMPLATE.md - this should provide basic skeleton for describing issue.
• setup .github/PULL_REQUEST_TEMPLATE.md this should describe succintly . Add checkmarks to include testcases, code conventions check and etc
• setup .github/CONTRIBUTING.md - copy style guides to this file and describe the guidelines.

Awesome @thammegowda . This will be very helpful.

I found OpenNLP templates very useful - https://github.com/apache/opennlp/tree/master/.github
