Adding Issue Tracking Document and Issue Template

[hai1337]

issue_tracking.md details both the triage and developer flows when it comes to tracking and resolving issues.

The ISSUE_TEMPLATE.md in this PR is related to this repo. There will be a similar one for osc.org with an additional section for the website. The code repo issue templates will be similar to normal defect info: expected behavior, actual behavior, steps to reproduce with the additional Status section.

Notice the labels added in each repository. The document repos contain slightly different labels, e.g., document repos will not have defect/product-code labels.

This issue addresses part of #51 by creating the template.
