Description

Introducing a new way to load packages from a trusted location in the filesystem.

• Packages are loaded from the filesystem. Useful for loading first party packages from modules/ (or contrib/) directory (-Dsolr.packages.local.dir=<path_to_contribs>).
• This mode (of loading packages from filesystem) doesn't go via ZK at all, and hence this mode can be used to cold start installations with few packages.
• This mode shall help the package management honour immutable infrastructure/deployments philosophy.
• This can ensure that only relevant packages are loaded and any vulnerabilities in contribs/libraries impact only a very small subset of users
• A unified view of packages irrespective of how you use it (local/ZK)
