Set up Large File Storage (LFS) for TeamForge repository

LFS is supported by TeamForge-Git/Gerrit integration 16.7.10-2.13.2 and later. LFS is controlled by two levels of configuration in TeamForge. First, integration level LFS configuration that provides default values for a given Gerrit instance. Second, repository level LFS configuration, which by default derives system level configuration that can be further adjusted.

In practice, it is assumed that the Gerrit integration server is LFS ready by default and one (Project Owner/Site Admin) decides on enabling LFS at the repository level with or without maximum object size limitation. This configuration scenario supports a model where LFS is enabled for specific repositories only while the rest of the system remains unaffected.
