"proxy_allowed" setting allows to specify the allowed IP address and IP
ranges that can send the proxy header. This setting combined with

that send the proxy header from a non listed IP

scp now properly handles virtual folders.

rsync is disabled for users with virtual folders: we execute a system

git is not allowed if the repo path is inside a virtual folder

c64c080159 fix test cases on Windows
We have to rework TestRelativePaths and TestResolvePaths if we want to run
them for Cloud Storage on Windows too: we use filesystem path while Cloud
Storage providers expect Unix paths.
On Windows is important to check the local filesystem so skip Cloud Storage
providers test cases for now

bcaf283c35 memory provider: load users from a dump file
The `memory` provider can load users from a dump obtained using the
`dumpdata` REST API. This dump file can be configured using the
dataprovider `name` configuration key. It will be loaded at startup
and can be reloaded on demand using a `SIGHUP` on Unix based systems
and a `paramchange` request to the running service on Windows.
