Feature request: Migration to search-able docs

[mc-xyz]

As a new user when working with hawkBit one has a very hard time. One reason for this is that the docs on the hawkbit-website generated from the site source code are not search-able.

The used hugo-material-docs is unmaintained.

One good alternative could be mkdocs-material which turned into a kind of a de-facto standard for modern Python packages cause of it's ease of setup and usage.
