Create a theme for paradox with Aiven branding

[mdedetrich]

What is currently missing?

Currently the doc generation (using paradox) is still using the basic theme

How could this be improved?

We should create a theme that uses Aiven brading/colouring to make the documentation more appeasing. We can use https://github.com/akka/akka-paradox as a reference.

An open point is whether or not we should put the paradox theme into a separate git repository. Doing so means we would be able to share the theme amongst multiple SBT projects (if we happen to have them in the future).

Is this a feature you would work on yourself?

• I plan to open a pull request for this feature
