support custom .JS and .CSS files for custom banner messages (white-labeling) (#1781) This PR introduces two new server configuration options, for providing a custom .JS and .CSS file. These can be used to show custom banner messages, add environment-dependent signals, or simply a corporate logo. ### Motivation (what problem I try to solve) I'm operating Woodpecker in multiple k8s clusters for different environments. When having multiple browser tabs open, I prefer strong indicators for each environment. E.g. a red "PROD" banner, or just a blue "QA" banner. Also, we sometimes need to have the chance for maintenance, and instead of broadcasting emails, I prefer a banner message, stating something like: "Heads-up: there's a planned downtime, next Friday, blabla...". Also, I like to have the firm's logo visible, which makes Woodpecker look more like an integral part of our platform. ### Implementation notes * Two new config options are introduced ```WOODPECKER_CUSTOM_CSS_FILE``` and ```WOODPECKER_CUSTOM_JS_FILE``` * I've piggy-bagged the existing handler for assets, as it seemed to me a minimally invasive approach * the option along with an example is documented * a simple unit test for the Gin-handler ensures some regression safety * no extra dependencies are introduced ### Visual example The documented example will look like this. ![Screenshot 2023-05-27 at 17 00 44](https://github.com/woodpecker-ci/woodpecker/assets/1189394/8940392e-463c-4651-a1eb-f017cd3cd64d) ### Areas of uncertainty This is my first contribution to Woodpecker and I tried my best to align with your conventions. That said, I found myself uncertain about these things and would be glad about getting feedback. * The handler tests are somewhat different than the other ones because I wanted to keep them simple - I hope that still matches your coding guidelines * caching the page sometimes will let the browser not recognize changes and a user must reload. I'm not fully into the details of how caching is implemented and neither can judge if it's a real problem. Another pair of eyes would be good.
