[EPIC] Support air-gapped installation

[nbykov0]

Steps:

• add a script which would collect images for each package
• add a script which would build/push images to private repo with correct names
• add nessesary stuff to packages' helm charts so that default images and pullSecrets could be overridden from a single point

Options:

• Full air-gap-ready distributive, with all images included
• Script that downloads all required for installation, then user can move it to an air-gapped infra and deploy there

This feature is valuable for large teams. There's a lot of work to do, so it should be an epic, split into multiple smaller issues.

@kvaps this epic is about implementing a dedicated docker registry for every image, and related stuff.
