Bugfixes

• Fix a memory leak which would occur any time loki.process had its configuration reloaded. (@ptodev)

  and if you use this exact function in your config, then you will need to rename your module. (@wildum)

• Fix an issue where nested import.git config blocks could conflict if they had the same labels. (@wildum)

• Fix an issue where loki.source.docker stops collecting logs after a container restart. (@wildum)
