[SDFAB-872] Allow to use local maven cache via env variable

If USE_LOCAL_SNAPSHOT_ARTIFACTS=true while we are building from source code, it will use the 
snapshot artifacts in local maven cache rather than fetching from remote repositories. It is not 
effective when we are not building from source code.
