Vendormanagement for Repository

[dragonchaser]

We need a vendor-management in the style of zypper that allows us to deal with charts of the same name/software coming in through different repositories.

e.g.

repoA provides prometheus 1.6.0 without any annotations

repoB provides prometheus 1.6.0 with customized annotations

expected behaviour: first come first serve, install from repoA desired behaviour: allow the user to prefer the installation from repoB over repoA
