* Added TLS support for web

- Added optional configurations `cert_file` and `key_file` to run web server with https

Signed-off-by: Dmytro Bondar <git@bonddim.com>

* Helm chart update

- Refactored Ingress to use one host only (`config.web.external_url` is required)
- Added Certificate resource template (secret is mounted to container into `/app/certs/`)
- Added support for service with mixed protocols (exposes UI and Wireguard ports on same IP)
- Added helm-docs target to makefile
- Changed pod labels to use selectorLabels
- Removed default probes (app runs without healthy web)
- Removed sections from README
