Using absolute paths in require calls

[janodvarko]

It would be great to have unified approach to module paths we are passing to require calls. We are currently mixing absolute and relative paths, which doesn't seem ideal.

Examples:

require("devtools/client/shared/vendor/react-prop-types");`
require("../utils/request-utils");

Preferring absolute paths might have positive impact:

• easy to lint
• easier refactoring (easier to find consumers of give module)
• easier to handle ES Modules and import
• easier search in general

WDYT?
