Which specifications should be added or completed

[vhtq18w]

Now we have only created a small part of UKUI project specifications, include:

• issuse label specification.

In-progress or planned specifications include:

• issuse report specification(report template)
• license specification(which licenses should be used for the UKUI's projects)
• code style spcification(unified c/c++ code style)

In addition, what aspects should we have specification? Such as:

• What specifications should be written for unified documentation?
• Which principles should be used when code have conflicts?
• Does CI need specification?

I think it would be better to discuss a more detailed list.
