Setup basic repository information

We have found missing basic repository settings/information. Please, consider changing following:
- [ ] Default template references inside `README.md` file
```
If you want to add label to almost all resources which has a deployment like `nest-prisma-template`, you can use this
Usually secret has a name `nest-prisma-template-database-secret`, but you have to specify it without app name.
bratiska-cli build_kustomize --deployment nest-prisma-template
bratiska-cli build_kustomize --host nest-prisma-template.example.com
bratiska-cli build_kustomize --image harbor.example.com/standalone/nest-prisma-template/master-4a18e16-richi
bratiska-cli deploy --deployment=nest-prisma-template-super-duper
bratiska-cli deploy --dry_run --image harbor.bratislava.sk/standalone/nest-prisma-template:bratiska-cli-3f3ce4fd14c76138a081596b2987a81f18a3c747-master-untracked --kustomize ./kubernetes/base
bratiska-cli deploy --image harbor.bratislava.sk/standalone/nest-prisma-template:bratiska-cli-3f3ce4fd14c76138a081596b2987a81f18a3c747-master-untracked
if you want to just use whatever image, then after `--image` flag type app package name, like `nest-prisma-template`

```
Remove any references on default template file, or if never changed from default `README.md`, please write one specific to the project.
