Add support for partners

[KaloyanTanev]

🎯 Problem to be solved

An approach that was taken to ease the setup for a partner organisation (Lido) was to create a fork of this repository and configure it for their specific needs. However, this is hard to scale solution - this repo is constantly changing and having to replicate that to all future partner repos is not feasible.

It would be beneficial if this repository can accommodate different partners and setups, so that everyone can use it and easily tweak what they want to use. Start with an implementation of the custom setup we have for Lido and make it easy for them to use the CDVN repo, instead of the LCDVN repo.

moving it back to the backlog, since our lcdvn strategy changed.
