feat(disk-cache): rewrite diskcache backend to be k8s and NFS safe. We no longer use diskcache lib, but instead a homebrew solution that uses redis lock and simple filesystem storage

make: synced makefiles

fix(configs): removed waitress as a default runner for web service on development. One of the big issues discovered receantly was due to waitress vs gunicorn differences on handling requests. Since gunicorn has a nice dev mode with code reloader we should use it as a default runner so we can avoid such issues in the past where dev setup runned different workers than production.

fix(vcsserver): make serializer consistent like in rhodecode

fix: svn, remove accidentally merged strict svn checks.
