In order to test this functionality, we had to expose the `BranchHead()`
through an API endpoint
```
GET /repos/{repo_id}/branches/{branch}/head
```
The response is a string that contains the latest commit hash of the
requested branch.
for now it's not clear defined, what to do on an unsupported event.
e.g. gitea webhook panel shows 500 error and no message.
now we have a successful webhook and a message to show an info
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.

### 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.
Add Kubernetes Deployments and StatefulSet update and Dockle Scan Plugins.
For Kubernetes plugin, I based on the Drone unmaintened Kubernetes
plugin and took the statefulset management evolutions. I added sync/wait
and force redeploy capabilities + updates dependencies
For Dockle plugin, I took example on Trivy plugin.
